Cryptocurrencies are digital or virtual assets that use cryptographic techniques to secure transactions and control the creation of new units. Unlike traditional money issued by governments, cryptocurrencies operate on distributed networks using blockchain technology.
A cryptocurrency is a digital asset recorded on a distributed ledger. Ownership is proven by a private key, and the validity of records is ensured by network consensus. Issuance and circulation require no central issuer—the network itself validates transactions and creates new units according to programmatic rules.
The term "crypto" refers to the encryption methods that protect these networks—specifically, public-key cryptography allows users to send and receive funds without intermediaries like banks. The defining feature is that no single authority controls the network. Instead, transactions are verified by a distributed network of computers (nodes) following agreed-upon rules. This removes the need to trust a central institution and, theoretically, makes the system resistant to censorship or single points of failure.
Blockchain is the underlying technology that makes most cryptocurrencies possible. Think of it as a shared ledger that records every transaction across a network of computers. When someone sends cryptocurrency, the transaction is broadcast to all nodes. These nodes group pending transactions into a "block," which is then added to the existing chain of blocks—hence the name blockchain.
Core elements: blocks, hash links, consensus mechanisms (PoW/PoS), and public verifiability of history. Immutability is achieved through cryptographic chains and the economic cost of attacking the network. According to NIST's blockchain basics, these properties create a tamper-evident record.
Three principles make blockchain powerful:
Decentralization means no single entity controls the ledger. Copies exist across thousands of nodes worldwide, so altering the history would require simultaneously compromising the majority of them.
Consensus mechanisms (like Proof of Work or Proof of Stake) determine how nodes agree on which transactions are valid. Bitcoin miners, for example, compete to solve complex mathematical puzzles; the first to succeed adds the next block and earns newly minted bitcoin as a reward. Ethereum transitioned from PoW to PoS in 2022, replacing energy-intensive mining with validators who stake coins.
Immutability ensures that once a block is added, changing it becomes computationally impractical. Each block contains a cryptographic hash of the previous block, creating a chain where altering one block invalidates all subsequent ones.
This architecture provides transparency (anyone can inspect the ledger) and security (fraudulent changes are quickly detected and rejected by honest nodes).
Traditional fiat currencies—euros, dollars, zlotys—are issued and regulated by central banks. Governments control their supply, set interest rates, and enforce legal-tender status. Cryptocurrencies flip this model:
|
Aspect |
Crypto |
Fiat |
|
Transfers |
P2P without bank schedules, 24/7 settlement, global reach without correspondent banks |
Business hours, SWIFT networks, correspondent bank delays |
|
Custody |
Self-custody (you hold keys) or custodial services (provider holds keys) |
Bank holds funds; customer-service recovery possible |
|
Fees |
Network fee + provider markup; varies with network congestion and payment method |
Wire fees (€15–€50 SWIFT), card fees (1–3%), typically fixed regardless of network load |
Transfers: Sending cryptocurrency can happen 24/7 without bank holidays or intermediaries. Bitcoin transactions settle globally without requiring correspondent banks or SWIFT networks. That said, network congestion can temporarily increase fees or slow confirmations.
Custody: With fiat, your bank holds your money; with crypto, you (or a custodian you trust) control the private keys. Losing those keys means losing access permanently—there's no customer-service hotline to reset your password.
Fees: International fiat transfers via SWIFT can cost €15–€50 and take days. Crypto on-ramps and off-ramps (the conversion between fiat and digital assets) also charge fees, but once you're holding crypto, peer-to-peer transfers are often cheaper and faster, especially for cross-border payments. For real-time fee comparisons, check our currency rates page.
The trade-off is volatility. Fiat currencies fluctuate modestly; major cryptocurrencies can swing 5–10% in a day. That volatility creates opportunities for traders but complicates everyday use—hence the rise of stablecoins, which we'll cover next.
Not all cryptocurrencies serve the same purpose. The market has naturally segmented into distinct categories based on technology, use case, and design philosophy.
Bitcoin remains the original and most recognized cryptocurrency. Launched in 2009 by the pseudonymous Satoshi Nakamoto through the Bitcoin whitepaper, it introduced the world to decentralized digital money. Key features include:
Limited supply of 21 million coins: Only 21 million bitcoins will ever exist. As of October 2025, roughly 19.7 million have been mined. This scarcity is enforced by Bitcoin's code and is central to its value proposition as "digital gold."
PoW mechanism and censorship resistance: Bitcoin's Proof-of-Work consensus makes attacking the network extraordinarily expensive—the computational power securing Bitcoin exceeds that of any other blockchain. High liquidity on major platforms ensures tight spreads and deep order books.
Store of value narrative: Bitcoin's primary use case has shifted from "peer-to-peer cash" to "store of value." Institutional adoption—through spot ETFs (launched in the US in January 2024), corporate treasuries, and nation-state holdings—has reinforced this role.
Limitation: Network throughput constraints (approximately 7 transactions per second) and energy consumption of PoW consensus remain subjects of debate. Bitcoin prioritizes security and decentralization over transaction speed.
Bitcoin's simplicity is both strength and limitation. It doesn't support smart contracts or complex applications, but that focus on security and decentralization has kept it the benchmark against which all other cryptocurrencies are measured.
"Altcoin" is shorthand for "alternative coin"—any cryptocurrency that isn't Bitcoin. This category is vast and includes assets with radically different goals:
Ethereum (ETH) pioneered smart contracts—self-executing programs that run on the blockchain. Ethereum transitioned to Proof of Stake, supports smart contracts and dApps, and scales through Layer-2 solutions like Arbitrum and Optimism. This opened the door to decentralized applications (dApps), decentralized finance (DeFi), and NFTs. As documented in Ethereum's developer resources, its flexibility has made it the leading platform for developers.
Litecoin (LTC) was created in 2011 as a faster, lighter version of Bitcoin. Oriented toward rapid settlements with PoW and lower fee burden—transactions confirm in roughly 2.5 minutes (versus Bitcoin's 10), and total supply is capped at 84 million coins. Litecoin has served as a testing ground for Bitcoin upgrades and remains popular for payments where speed matters.
XRP (Ripple) focuses on facilitating cross-border payments for financial institutions. Used in scenarios of transborder transfers and liquidity between currencies—unlike Bitcoin or Ethereum, XRP doesn't rely on mining; instead, a consensus protocol validates transactions among trusted nodes. It's fast and cheap but more centralized, which has sparked debate about whether it fits the decentralized ethos of crypto.
Risks: Technological protocol updates and regulatory uncertainty for individual assets. Smaller altcoins may face liquidity issues, development abandonment, or delisting from major exchanges if they fail to meet evolving compliance standards.
Altcoins span everything from privacy coins (Monero) to meme coins (Dogecoin). Some offer genuine innovation; others are speculative experiments. The key is understanding what problem each altcoin claims to solve and whether its technology delivers.
Stablecoins bridge the gap between volatile crypto and stable fiat. They're designed to maintain a 1:1 peg with a reference asset, usually the US dollar.
Fiat-backed models rely on reserves and issuer reporting. For every stablecoin issued, the issuer claims to hold an equivalent amount of dollars (or dollar-denominated assets like Treasury bills) in reserve. Users trust that they can redeem USDT or USDC for $1 at any time. Transparency varies: Circle publishes monthly attestations from Grant Thornton showing USDC reserves, while USDT has faced scrutiny over its reserve composition.
Crypto-collateralized stablecoins like DAI use other cryptocurrencies as backing. DAI is minted on Ethereum when users lock up collateral (often ETH or other tokens) in smart contracts. Because crypto is volatile, these systems require over-collateralization—you might lock $150 of ETH to mint $100 of DAI. Algorithms automatically liquidate undercollateralized positions to maintain the peg. Details are available in MakerDAO's documentation.
Algorithmic stablecoins attempt to maintain stability through supply adjustments rather than reserves. These have a checkered history—TerraUSD (UST) famously collapsed in May 2022, wiping out billions in value. As of 2025, purely algorithmic stablecoins remain marginal due to inherent instability risks.
Risks: Peg dependency on reserves, counterparty dependence, and in the EU, applicability of EMT/ART norms under MiCA. Only stablecoins meeting MiCA's reserve and audit requirements can be marketed to EU retail users.
Stablecoins are crucial for on-ramps and off-ramps. They let traders move in and out of volatile positions without converting back to fiat, reducing friction and fees. For international remittances or commerce, stablecoins offer speed and low cost with manageable risk.
"Tokens" often gets used interchangeably with "coins," but there's a technical distinction. Coins (Bitcoin, Litecoin, Ether) have their own blockchains. Tokens are built on top of existing blockchains, most commonly Ethereum (using the ERC-20 standard) or newer platforms like Solana or Polygon.
Utility tokens grant access to a product or service. For example, Filecoin (FIL) lets users pay for decentralized storage, while Chainlink (LINK) is used to pay for oracle services that bring off-chain data onto blockchains. Utility tokens provide access to protocol functions.
Governance tokens give holders voting rights in decentralized protocols. Uniswap (UNI) token holders can propose and vote on changes to the Uniswap exchange. Governance tokens grant voting rights; in practice, participation is often low and large holders wield disproportionate influence.
Security-like tokens represent ownership or entitlement to cash flows. Under most jurisdictions—including the EU's MiCA framework—these may be regulated as financial instruments. Some projects issue tokens that resemble equity or bonds. Security-like tokens carry characteristics of investment instruments; regulatory clarity continues to evolve.
Risks: Information asymmetries and value dependency on ecosystem viability. Token projects may fail due to poor governance, security exploits, or lack of genuine utility. Due diligence requires examining the whitepaper, audits, team track record, and community engagement.
Tokens proliferated during the ICO (Initial Coin Offering) boom of 2017–2018, when projects raised funds by selling new tokens. Many failed or turned out to be scams, but the token model remains central to DeFi, NFTs, and Web3 applications.

Ranking cryptocurrencies isn't as straightforward as sorting by market capitalization. A comprehensive methodology considers:
Liquidity and spreads on major platforms: Can you buy or sell significant amounts without moving the price? Bitcoin and Ethereum dominate here, with deep order books across dozens of exchanges. Smaller altcoins may have high nominal market caps but thin liquidity, making large trades difficult.
Breadth of application (use-case): How widely is the asset used? This includes institutional holdings, merchant acceptance, DeFi integrations, and developer activity. Ethereum's vast ecosystem of dApps gives it adoption beyond speculation; Bitcoin's growing use in treasury reserves signals institutional confidence.
Ecosystem maturity and developer activity: Measured by GitHub commits, active addresses, and protocol upgrades. Ecosystems with sustained development and growing user bases demonstrate long-term viability.
Regulatory framework fit for EU service providers (CASP): With MiCA and other frameworks tightening, assets that can demonstrate compliance (transparent reserves for stablecoins, KYC/AML for exchanges) are better positioned. Projects operating in regulatory gray areas face delisting or restriction risks.
Data transparency: Availability of on-chain metrics, audit reports, and public documentation. Opaque projects raise red flags.
The examples below are presented neutrally by category—without recommendations. Inclusion does not constitute endorsement, and exclusion does not imply criticism.
Bitcoin entered 2025 with a clearer narrative than ever: digital gold for a digital age. As of October 2025, Bitcoin's market capitalization stands at approximately $1.3 trillion, representing roughly 42% of the total cryptocurrency market (total market ~$3.1 trillion). Spot Bitcoin ETFs launched in the US in January 2024, bringing institutional capital and making BTC accessible through traditional brokerage accounts. This legitimization has reduced (but not eliminated) volatility.
Key drivers for Bitcoin in 2025:
Macro uncertainty: Persistent inflation concerns and currency debasement fears in developed economies push some investors toward scarce assets. Bitcoin's fixed supply appeals to those skeptical of central-bank policy.
Nation-state adoption: El Salvador adopted Bitcoin as legal tender in 2021; other countries have explored sovereign Bitcoin reserves. While these experiments remain small-scale, they signal growing acceptance at the state level.
Halving cycle dynamics: Bitcoin's programmed supply reductions (halvings) occur roughly every four years. The April 2024 halving cut block rewards from 6.25 to 3.125 BTC, reducing new supply. Historically, halvings have preceded price appreciation as supply tightens while demand holds or grows.
Bitcoin's simplicity is its strength. It does one thing—secure, decentralized money—exceptionally well. That focus has kept it the market leader by capitalization and mindshare.
Beyond Bitcoin, several segments stand out in 2025:
Smart-contract platforms: Ethereum remains dominant with a market cap of approximately $420 billion (October 2025), but competitors like Solana, Avalanche, and BNB Chain have carved niches.
Ethereum: Layer-2 solutions (Arbitrum, Optimism, Base) now process millions of transactions daily at ~$0.10–$0.50 per transaction, compared to Ethereum mainnet fees of $1–$20. Block time: ~12 seconds. Trade-off: L2s introduce additional trust assumptions.
Solana: ~400ms block time, $0.00025 average transaction fee, optimized for high-frequency trading and NFTs. Trade-off: History of network outages and concerns about validator centralization.
BNB Chain: Lower fees than Ethereum mainnet, strong integration with Binance ecosystem. Trade-off: More centralized governance model.
The race isn't winner-take-all; different platforms optimize for different trade-offs between speed, security, and decentralization.
Stablecoins' central role: USDT and USDC combined represent approximately $140 billion in market cap (October 2025). They're the lifeblood of crypto exchanges, enabling traders to move between positions quickly. Regulatory scrutiny has intensified—MiCA requires issuers to hold reserves in low-risk assets and publish regular audits. This professionalization benefits established players like Circle (USDC issuer) while squeezing out opaque competitors.
Layer-2 solutions: As Ethereum's base layer remains expensive for small transactions, Layer-2 networks process transactions off-chain and settle batches on Ethereum. This reduces fees while inheriting Ethereum's security. Layer-2 total value locked (TVL) exceeded $40 billion in 2025, with billions locked in DeFi protocols on these networks.
The 2025 landscape rewards projects with genuine utility, strong developer communities, and regulatory compliance. Speculative hype hasn't disappeared, but it's a smaller share of the market than in previous cycles.
Here are large-cap examples across major categories, presented without endorsement:
Store of value: Bitcoin (BTC) dominates this category by market cap and narrative strength.
Smart-contract platforms: Ethereum (ETH) leads, followed by major Layer-2 solutions (Arbitrum, Optimism), BNB Chain, Solana (SOL), and Cardano (ADA). Each has trade-offs in speed, decentralization, and ecosystem size.
Payment-focused networks: Litecoin (LTC) for fast PoW settlements, XRP for cross-border liquidity, Stellar (XLM) for remittances.
Stablecoins: Issuers with regular reserve reporting—examples include assets with transparent backing and third-party attestations.
Note: This list is not exhaustive and carries no recommendation. Specific properties depend on the protocol and issuer conditions. Markets change, projects evolve, and regulatory shifts can elevate or undermine any asset. Always conduct your own research and consider your risk tolerance.
Cryptocurrency prices can swing violently. Bitcoin, the most stable by crypto standards, has seen 20–30% corrections within weeks. Altcoins and smaller tokens can drop 50% or more in days. This volatility creates opportunities but also significant risk.
Spreads matter when you buy or sell. The spread is the difference between the highest bid and lowest ask price. On liquid assets like BTC and ETH, spreads are tight—often 0.1–0.3% on major exchanges. Illiquid tokens might have spreads of 5–10%, meaning you lose money the moment you buy.
Venues vary in reliability. Established exchanges like Coinbase, Kraken, and Binance offer deep liquidity and insurance on custodial balances. Smaller or newer platforms may have lower fees but carry higher counterparty risk—if the exchange is hacked or collapses, your funds could be lost. The 2022 collapse of FTX (then the third-largest exchange) demonstrated this risk vividly.
Counterparty risk extends beyond exchanges. DeFi protocols, while trustless in theory, can have bugs or governance attacks. In 2022–2023, multiple DeFi platforms experienced exploits (e.g., Ronin Bridge $625M hack, Wormhole $325M exploit) or insolvencies, erasing user funds. Due diligence means checking audits, understanding the protocol's governance, and never investing more than you can afford to lose.
Getting money into and out of cryptocurrency involves several layers of fees:
Card payments (Visa/Mastercard) are fast but expensive. Expect 3–5% fees when buying crypto with a credit or debit card. This covers payment-processor fees, fraud risk, and exchange markup. For small purchases or urgent needs, card payments are convenient; for larger amounts, bank transfers are smarter.
SEPA transfers within the EU are typically free or cost a few euros, and many exchanges accept them with 0–1% fees. Settlement takes 1–2 business days. SEPA is the most cost-effective option for EU residents making larger purchases.
SWIFT transfers (for international payments outside SEPA) can cost €15–€30 plus intermediary bank fees and take 3–5 days, but they unlock global markets.
On-ramp fees are what you pay to convert fiat into crypto. Platforms like Paycot specialize in this—offering competitive rates, multiple payment methods, and compliance with EU regulations. Look for transparent fee structures; hidden markups in the exchange rate can cost more than advertised fees.
Off-ramp fees (selling crypto for fiat) mirror on-ramp costs. Withdrawing to a bank account or card incurs processing fees, usually 1–2% plus a flat charge. Some platforms offer free SEPA withdrawals above a minimum threshold.
Minimizing fees means planning ahead: use bank transfers for large amounts, batch transactions to reduce fixed costs, and compare platforms. A few hours of research can save hundreds of euros on a sizable transaction.
Ownership in cryptocurrency is defined by control of private keys. Understanding custody options is essential for security:
Self-custody means you hold your private keys, typically in a software wallet (MetaMask, Exodus) or hardware wallet (Ledger, Trezor). You have complete control and no counterparty risk, but you're also responsible for security. Lose your keys or seed phrase, and your funds are gone forever. Get phished or hacked, and there's no recovery.
Custodial services (exchanges, platforms like Paycot) hold your keys for you. This is convenient—no need to manage complex backups—but introduces counterparty risk. If the custodian is hacked, goes bankrupt, or freezes your account, you're at their mercy. Reputable custodians mitigate this with insurance, cold storage, and regulatory compliance.
Hot vs. cold wallets: Hot wallets are connected to the internet, making them convenient for frequent transactions but vulnerable to hacking. Cold wallets (hardware devices or paper wallets) stay offline, offering maximum security at the cost of accessibility. Best practice for significant holdings is cold storage, with a hot wallet for day-to-day spending.
Your choice depends on your needs. Active traders may prioritize custodial convenience; long-term holders often prefer self-custody with hardware wallets. Hybrid approaches—keeping most funds in cold storage and a smaller amount on exchanges—balance security and usability.
Verify domain and SSL before entering credentials or payment information
Store seed phrases offline—never share with third parties or store in cloud services
Use cold storage or multi-signature wallets for significant amounts (>$10,000 equivalent)
Review limits and fees before executing transactions; ensure you understand total costs
Use providers with KYC/AML procedures for on/off-ramp services to ensure regulatory compliance

The European Union has established the world's most comprehensive regulatory framework for digital assets. Three primary regulations govern crypto activity in the EU:
MiCA (Markets in Crypto-Assets Regulation): Framework for classifying crypto-assets and requirements for service providers, with emphasis on EMT/ART tokens and "other" crypto-assets. Full text: Regulation (EU) 2023/1114.
AMLD5 (Fifth Anti-Money Laundering Directive): Baseline KYC/AML procedures for exchanges and custodial providers. Details: Directive (EU) 2018/843.
Transfer of Funds Regulation (Travel Rule): Transmission of information about sender and recipient when transferring crypto-assets between providers. See Regulation (EU) 2023/1113.
For users, this means identity verification when accessing services and transparent operations at entry and exit points of the crypto ecosystem.
The Markets in Crypto-Assets Regulation (MiCA) came into full effect throughout 2024–2025, creating the world's most detailed crypto rulebook. MiCA distinguishes three main categories:
Asset-Referenced Tokens (ARTs) are stablecoins backed by a basket of assets (e.g., a mix of fiat currencies or commodities). Issuers must be authorized, hold reserves, and publish regular reports. Only authorized issuers can market ARTs to EU consumers.
E-Money Tokens (EMTs) are stablecoins pegged 1:1 to a single fiat currency (like USDC or USDT pegged to USD). Issuers must hold reserves in segregated accounts at credit institutions and ensure redemption at par value. EMT issuers need either an e-money institution license or a credit institution license under EU banking law.
Other crypto-assets include everything else—Bitcoin, Ethereum, utility tokens, NFTs, governance tokens. These don't face the same reserve requirements as ARTs/EMTs, but providers (exchanges, custodians) must be authorized as Crypto-Asset Service Providers (CASPs).
CASP obligations under MiCA include:
Minimum capital requirements (€50,000–€150,000 depending on services offered)
Governance standards and conflict-of-interest management
Custody safeguards: CASPs must separate client assets from their own
Professional indemnity insurance or comparable guarantee
Regular reporting to national competent authorities
Complaint handling and investor protection measures
MiCA aims to protect consumers, prevent market abuse, and ensure financial stability. It also grants firms licensed in one EU member state a "passport" to operate across the bloc—reducing fragmentation and compliance costs. For a registry of authorized CASPs, see ESMA's MiCA registers.
The Fifth Anti-Money Laundering Directive (AMLD5) extended traditional AML/KYC rules to cryptocurrency platforms. Exchanges, wallet providers, and fiat-crypto services must:
Conduct customer due diligence (CDD): Verify the identity of users through government-issued ID, proof of address, and sometimes biometric checks. Enhanced due diligence applies to high-risk customers or transactions (e.g., large cash transactions, customers from high-risk jurisdictions).
Screen for sanctions and PEPs: Platforms must check users against EU and international sanctions lists (OFAC, UN, EU financial sanctions) and identify politically exposed persons (PEPs) who pose higher corruption risk.
Monitor transactions: Suspicious activity—large, rapid, or unusual transaction patterns—triggers reporting obligations to national financial intelligence units (FIUs). Platforms use automated transaction monitoring systems to flag anomalies.
Record-keeping: Customer data and transaction histories must be retained for at least five years after the end of the business relationship.
AMLD5 brought crypto into the same regulatory perimeter as banks, curbing its use for money laundering or terrorism financing. For users, this means providing personal information—anonymity is no longer feasible when using regulated on-ramps or exchanges.
The EU's Transfer of Funds Regulation (Regulation 2023/1113), commonly called the Travel Rule, requires that crypto transfers include information about the sender (originator) and receiver (beneficiary).
When you send cryptocurrency from a regulated platform (a CASP) to another CASP or to a self-hosted wallet, the sending platform must:
Collect and verify your identity (already done through KYC)
Obtain the recipient's name and wallet address
Transmit this information to the receiving CASP (if the recipient uses a regulated platform)
For transfers to self-hosted wallets exceeding €1,000, verify that the wallet belongs to the customer
This mirrors existing rules for wire transfers and is designed to prevent anonymous crypto flows that could be used for illicit purposes. For person-to-person transfers, both parties must be identifiable.
The Travel Rule complicates self-custody: if you withdraw funds from an exchange to your own wallet, the exchange must verify that the destination wallet belongs to you. Some platforms require you to whitelist addresses or prove ownership (by signing a message with the private key) before allowing withdrawals.
Critics argue the Travel Rule undermines privacy and self-sovereignty—core tenets of cryptocurrency. Proponents counter that regulation is necessary for mainstream adoption and to prevent crypto from becoming a haven for crime.
Poland implemented MiCA ahead of many EU states. Since 2024, cryptocurrency service providers operating in or targeting Polish users must register with the Ministry of Finance as Virtual Asset Service Providers (VASPs).
Provider registration in Poland's virtual currency services registry confirms compliance with local requirements. Company data and registration numbers are displayed in our footer and on the About us page.
Registered VASPs appear in the official registry (the "Register of Virtual Currency Activities"), which you can verify online. Registration requires:
Demonstrating compliance with AML/KYC procedures
Appointing a compliance officer
Maintaining adequate capital and insurance
Submitting to periodic audits
For users, a VASP registration number signals that the platform meets Polish regulatory standards. Paycot operates under certificate number 2401-CKRDST.4225.200.2024 (registry number RDWW 1226), demonstrating full compliance with Polish and EU law.
Unregistered platforms operating in Poland face fines or criminal penalties. If you're based in Poland or another EU country, using a registered, MiCA-compliant platform protects you with clearer legal recourse if something goes wrong.
This section uses Paycot as a case study to illustrate how regulated fiat-to-crypto platforms operate. While we reference our own service, the general process applies to most MiCA-compliant CASPs in the EU.
Getting started on a regulated platform takes just a few minutes. The process is designed for security and compliance while remaining user-friendly.
Step-by-step onboarding:
Sign up: Visit the platform's official domain (for Paycot: paycot.com) and create an account with your email and a strong password. You'll receive a confirmation link to verify your address.
Enable two-factor authentication (2FA): After logging in, activate 2FA using an authenticator app (Google Authenticator, Authy, etc.). This adds a critical layer of security—even if someone steals your password, they can't access your account without your phone.
Complete KYC: MiCA and AMLD5 require identity verification. You'll upload:
Government-issued ID (passport, national ID card, or driver's license)
Proof of residence (utility bill, bank statement—dated within the last three months)
Selfie or liveness check (to prevent identity fraud)
The system uses automated verification for most users, and approval typically completes within 5–15 minutes. High-value transactions may trigger enhanced due diligence, which can take a few hours to one business day.
Set transaction limits: New accounts start with conservative limits (e.g., €1,000 per day). As you verify additional information or build a transaction history, limits increase automatically. Enterprise users can request higher limits by contacting support.
KYC isn't just regulatory theater—it protects you. Verified accounts are harder for fraudsters to compromise, and they enable faster customer support if you encounter issues.
Regulated platforms support multiple payment methods, balancing speed, cost, and accessibility:
Visa and Mastercard: Buy crypto instantly using your debit or credit card. Transactions process within minutes, making this ideal for urgent purchases. Fees are higher (typically 3.5–4.5%) due to card-network costs and chargeback risk, but the convenience often justifies it for amounts under €500. Note that credit-card purchases may incur cash-advance fees from your bank—check with your issuer.
SEPA transfers: For EU users, SEPA is the most cost-effective option. Transfer euros from your bank account to the platform's account (IBAN provided at checkout), and funds arrive in 1–2 business days. Fees are minimal—usually 0.5–1%—and there's no markup from payment processors. Amounts over €1,000 benefit significantly from SEPA's lower cost structure.
SWIFT transfers: Users outside the SEPA zone can send funds via international wire. SWIFT is slower (3–5 business days) and more expensive (€15–€30 sender fee plus €10–€20 intermediary-bank fees), but it works from nearly any country. Ensure you include the correct reference code so the platform can match the payment to your account.
When selling crypto (off-ramping), you can withdraw fiat to your bank account via SEPA or SWIFT, or to a Visa/Mastercard. Push-to-card withdrawals arrive in 30 minutes to 24 hours and are useful for accessing funds quickly, though fees are slightly higher (1.5–2%) than bank transfers.
The exchange interface is built for clarity and speed:
5-step process:
Register your account and complete KYC (see above)
Select action: Choose "Buy" (fiat→crypto), "Sell" (crypto→fiat), or "Swap" (crypto→crypto without fiat conversion)
Specify asset and payment method:
For Buy: Enter amount in fiat (e.g., €500) or crypto (e.g., 0.01 BTC)
Select payment method: Visa/Mastercard or SEPA/SWIFT
The system displays the exact exchange rate, network fee, service fee, and final amount you'll receive
Verify total amount and fees before confirmation: Exchange rates fluctuate constantly. The platform locks in a rate for a short window (typically 30–90 seconds), giving you time to review. If you wait too long, you'll get a new quote reflecting current market conditions. All fees are displayed transparently—no hidden spreads.
Complete operation and receive confirmation:
For card purchases: Enter card details (processed through PCI-DSS-compliant gateways)
For bank transfers: You'll receive IBAN details and a unique reference number
Once payment is confirmed, cryptocurrency is sent to your specified wallet address
For on-platform storage, it appears in your account instantly
For external wallets, blockchain confirmation times apply (2–30 minutes for most assets)
Note: Final cost depends on exchange-rate fluctuations, network fees (gas), and your chosen deposit/withdrawal method. Always review the summary before confirming.

Coins are typically native assets of their own networks and are used to pay fees or secure the network through staking/mining. Examples: Bitcoin (Bitcoin blockchain), Ether (Ethereum blockchain), SOL (Solana blockchain).
Tokens are issued on top of existing networks and provide access to functions or rights within an ecosystem. Examples: USDT (issued on Ethereum, Tron, and other chains), UNI (governance token on Ethereum).
Specific properties depend on the protocol and issuer terms. For users, the distinction matters most for understanding dependencies: if Ethereum experiences downtime, all ERC-20 tokens (including USDT on Ethereum) are affected. Sending tokens also requires a small amount of the underlying coin (e.g., sending USDT on Ethereum costs ETH for gas fees).
Stablecoins are designed for stability, not absolute safety. Their risk profile depends on the backing mechanism:
Fiat-backed stablecoins (USDT, USDC, EURC): Hold reserves in cash and short-term government securities. USDC publishes monthly attestations from Grant Thornton. Under MiCA, EMT issuers must hold reserves in segregated accounts at EU credit institutions, reducing mismanagement risk. Risk: Issuer insolvency or reserve mismanagement could break the peg.
Crypto-collateralized (DAI): Backed by over-collateralized cryptocurrency deposits in smart contracts. Collateral is auditable on-chain, but extreme market volatility can trigger cascading liquidations. DAI survived the 2022 crypto crash because of its 150%+ collateralization ratio.
Algorithmic (TerraUSD—collapsed May 2022): Attempted to maintain peg through supply mechanisms without reserves. The Terra/LUNA death spiral demonstrated fatal flaws in this model. Avoid purely algorithmic stablecoins.
For everyday use—payments, remittances, short-term holdings—major fiat-backed stablecoins under MiCA regulation (USDC, EURC) present manageable risk. For large amounts or long-term storage, assess your comfort with issuer risk and consider diversifying across multiple stablecoins or holding a portion in less-volatile crypto.
There's no universal answer, but here's a risk-based framework:
Bitcoin is the most established entry point. Highest liquidity, longest track record (16 years), simplest architecture. If your goal is long-term value storage and you want to minimize technological complexity, Bitcoin is the default choice. Start with €100–€500 to learn how wallets and transactions work.
Stablecoins (USDC, EURC) allow you to experiment with blockchain technology without price risk. Ideal for understanding wallets, transaction fees, and platform interfaces before committing capital to volatile assets. Many beginners use stablecoins to "park" funds on-chain between trades.
Ethereum opens access to smart contracts, DeFi, and NFTs, but requires understanding gas fees and wallet interactions. Consider this after mastering Bitcoin or stablecoin basics. Start with a small amount (€50–€100) to learn without significant risk.
Avoid: Small-cap altcoins (market cap <$100 million), meme coins, any asset promising guaranteed returns, and projects with anonymous teams. Stick with top-20 assets by market cap until you can evaluate whitepapers, tokenomics, and on-chain metrics.
Risk management: Never invest more than you can afford to lose. Cryptocurrency is volatile and not suitable for emergency funds or short-term savings. Consider crypto a speculative allocation (5–15% of investable assets) rather than a core holding.
Yes. Cryptocurrency carries multiple risk vectors:
Price risk: Assets can drop 50–90% in bear markets (as seen in 2018 and 2022). Even Bitcoin, the most stable cryptocurrency, has experienced 80%+ drawdowns from peak to trough.
Custody risk: Losing your private keys means permanent loss of funds—there's no recovery. Conversely, custodial services (exchanges) can be hacked or go bankrupt (Mt.Gox 2014, FTX 2022).
Smart-contract risk: DeFi protocols can have bugs. The DAO hack (2016, $60M stolen) and countless DeFi exploits demonstrate code vulnerabilities.
Regulatory risk: Governments can ban certain cryptocurrencies, restrict on/off-ramps, or impose punitive taxation. China's 2021 mining ban caused short-term market disruption.
Scam risk: Ponzi schemes, rug pulls, and fake tokens are common. Bitconnect (2018), OneCoin, and countless ICO scams have defrauded billions.
Mitigation strategies: diversify across assets, use hardware wallets for long-term holdings, only invest disposable income, verify platform registration (VASP/CASP), avoid projects promising guaranteed returns, and educate yourself continuously.
Tax treatment varies by jurisdiction, but general EU principles apply:
Capital gains: Selling cryptocurrency for fiat typically triggers capital gains tax. In Poland, crypto gains are taxed at 19% (PIT-38 form). Holding periods don't affect the rate—unlike some countries, Poland doesn't offer long-term holding exemptions.
Income: Mining, staking rewards, and airdrops may be treated as income and taxed at progressive rates (17–32% in Poland).
VAT: Cryptocurrency-to-fiat exchanges are VAT-exempt across the EU (ECJ ruling, 2015). However, purchasing goods/services with crypto may have VAT implications.
Reporting: Many EU countries require disclosure of crypto holdings above certain thresholds. In Poland, gains must be reported annually via PIT-38.
Record-keeping: Maintain transaction records (date, amount, fiat value at time of transaction) for all buys, sells, and trades. Platforms like Paycot provide transaction history exports for tax purposes.
Disclaimer: This is not tax advice. Tax laws change frequently, and enforcement varies by jurisdiction. Consult a qualified tax advisor familiar with crypto regulations in your country.
