Quick Answer
To buy cryptocurrencies, you need a crypto wallet to receive your funds, a platform to make the purchase, and money available on your bank card or account.
Buying cryptocurrencies is simpler than it seems — but there are a few things you need to know before spending your first dollar. In short: cryptocurrencies work similarly to digital money, and a wallet is where you keep them and from where you can send or receive funds.
What you’ll find in this guide: We explain from scratch what cryptocurrencies are, how to choose a wallet, how to buy step by step, how to choose a safe platform, what fees you pay, and how to avoid scams.

What are cryptocurrencies?
Cryptocurrencies are digital assets that operate on blockchain technology and enable value transfers without intermediaries like banks. The most well-known are Bitcoin, Ethereum, USDT, XRP, and Solana.
💡 Practical example
Alex wants to send 0.01 BTC to a friend in Germany. He opens his wallet, enters his friend’s address and confirms. The transaction arrives within 10-60 minutes — whether it’s 3am or a weekend. No bank paperwork, no approval, no international transfer limits.
What you need before buying cryptocurrencies
1. 📱 A digital wallet
2. 🏦 A buying platform
A platform converts dollars or euros into crypto. There are custodial ones (Binance, Coinbase — they hold your keys) and non-custodial ones (coins go directly to your wallet). The difference matters enormously for security.
3. 💳 A payment method
Bank card (Visa/Mastercard) or bank transfer. Card is faster (minutes), bank transfer can be cheaper in fees. Some platforms also accept PayPal or Revolut.
⚠️ Important: Never send crypto to someone you don’t know. Never share your seed phrase or private key with anyone. Whoever holds them, controls the funds.
Custodial vs. Non-custodial — the most important decision
🏦 Custodial (Binance, Coinbase)
✓ Familiar interface, password recovery
✓ Access to trading features
✗ Platform holds your private keys
✗ Funds can be frozen
✗ Risk if platform goes bankrupt
🔓 Non-custodial (MoonPay, Abarai)
✓ You hold the private keys
✓ No one can freeze your funds
✓ Coins go directly to your wallet
✗ You are responsible for the seed phrase
✗ Lost seed phrase = lost funds
The FTX lesson: In November 2022, FTX — the world’s second largest exchange — suddenly collapsed. Millions of users lost access to their funds. Those who had withdrawn to personal wallets lost nothing. Those who had left everything on the platform lost everything. Whoever holds the private keys holds the crypto.
The 3 main ways to buy crypto
💳 Method 1 — By bank card (fastest)
Enter your wallet address, amount and card details. Processes in minutes. Pros: instant, simple, 24/7. Cons: slightly higher fees (4-8%). Best for: beginners, small amounts.
🏦 Method 2 — Bank transfer
Pros: lower fees (1-2%). Cons: takes hours or days. Best for: large amounts, planned purchases.
🤝 Method 3 — Crypto ATM
Buy with cash at a physical terminal. Pros: fast, no account needed. Cons: higher costs, requires physical visit.
| 💳 Card | 🏦 Bank transfer | 🤝 Cash ATM | |
|---|---|---|---|
| Speed | Minutes | Hours–days | Variable |
| Fee | 4-8% | 1-3% | 4-8% |
| Minimum | Any amount | Variable | Operator dependent |
| Best for | Beginners | Large amounts | Everyone |
How to create a crypto wallet
💻 Hot Wallet (software)
Apps on phone or desktop, internet-connected.
Trust Wallet — multi-chain, free, beginner-friendly
MetaMask — Ethereum and EVM networks
Exodus — clean interface, 260+ coins
✓ Free, easy to use
✗ Online = more vulnerable
✗ Online = more vulnerable
🔒 Cold Wallet (hardware)
Physical devices, offline, maximum security.
Ledger Nano S Plus — most popular, ~$79
Trezor Safe 5 — open-source, ~$169
✓ Maximum security, offline
✗ Costs money, more complex
✗ Costs money, more complex
📱 Create a Trust Wallet in 5 minutes
1. Download Trust Wallet from the App Store or Google Play.
2. Select “Create a new wallet”.
3. Write down the 12-word seed phrase on paper — not in your phone, not in email, not in the cloud.
4. Confirm the seed phrase in the app for verification.
5. Go to “Receive” for the desired coin and copy the address — this is what you’ll provide when buying.
🚨 Golden rule: The seed phrase (12-24 words) equals all the money in your wallet. Whoever holds it, controls the funds. Never photograph it, never save it digitally, never share it with anyone — not tech support, not anyone.
Which cryptocurrency should you buy?
| Coin | Best for | Risk | Staking |
|---|---|---|---|
| Bitcoin | Long-term value storage | Medium | No |
| Ethereum | Investment + staking | Medium | ~3-5% |
| USDT | Stable transfers | Low | Variable |
| XRP | Fast international payments | Medium | Limited |
| Solana | Speed + staking | High | ~7-15% |
| BNB | Binance ecosystem users | Medium | Yes |
| Cardano | Staking without lock-up | Medium | ~3-5% |
💡 Beginner recommendation: Bitcoin is the safest entry point — most well-known, most liquid, longest track record. For passive income via staking, add Ethereum or Solana. For stable transfers — USDT on TRC20 is the cheapest and fastest.
How to buy Bitcoin (BTC)
Bitcoin has a limited supply of 21 million coins, used primarily for long-term value storage. You don’t need a whole Bitcoin — you can start with any amount.
- Create a compatible wallet (Muun Wallet, Trust Wallet or Ledger) and copy the address from “Receive”.
- Enter the address on the platform and choose the amount.
- Pay by card — Bitcoin arrives in 10–60 minutes.
How to buy Ethereum (ETH)
Ethereum is the platform that runs thousands of decentralized apps. You can also stake ETH and earn ~3-5% annually. Ethereum addresses start with “0x”.
- Install MetaMask or Trust Wallet and copy your Ethereum address.
- Enter the address on the platform and select Ethereum Mainnet.
- Pay by card — ETH arrives in a few minutes.
How to buy USDT (Tether)
USDT is a stablecoin always worth ~$1. For small amounts and fast transfers, choose TRC20 (TRON): fees under $1, confirmation in 3 seconds.
- Open Trust Wallet, select USDT TRC20 and copy the address.
- Enter the address and verify the network is TRC20.
- Pay by card — USDT arrives within seconds.
How to buy XRP
XRP is built for fast international payments — confirms in 3-5 seconds. Important: every new XRP wallet needs a minimum of 10 XRP for activation, which stays locked permanently.
- Create an XRP wallet in Trust Wallet or Xumm and copy the address.
- Buy minimum 10 XRP for activation, plus the desired amount.
- Pay by card — XRP arrives within seconds.
How to buy Solana (SOL)
Solana confirms in under a second with fees under $0.01. Popular for staking (7-15% annually). The most popular Solana wallet is Phantom.
- Install Phantom (mobile or Chrome extension) and copy your SOL address.
- Enter the address on the platform.
- Pay by card — SOL arrives within seconds.
How to buy BNB
BNB is Binance’s native coin — used for fee discounts (25%) and paying gas on BNB Chain. Addresses are in 0x format, same as Ethereum.
- Open MetaMask or Trust Wallet on BNB Chain and copy the address.
- Verify the network is BEP20.
- Pay by card — BNB arrives within seconds.
How to buy Cardano (ADA)
Cardano offers accessible staking — 3-5% annually, no lock-up, withdraw anytime. Cardano addresses start with “addr1”.
- Install Eternl or Yoroi and copy your ADA address.
- Enter the address on the platform.
- Pay by card — ADA arrives within seconds.
How to choose a safe crypto buying platform
Not all platforms are the same. Before depositing money anywhere, check these 5 criteria:
✓Regulatory authorizations: look for MiCA (EU), FinCEN (US), FCA (UK). These prove the platform has been vetted by regulators.
✓User reviews: check Trustpilot and Google. More than 500 reviews with an average above 4/5 is a good sign.
✓Transparent fees: shown before confirming. No hidden fees discovered after the transaction.
✓Real support: phone, email or live chat — not just a FAQ page. You want to be able to reach a real person if something goes wrong.
✓Non-custodial model: the platform sends crypto directly to your wallet, doesn’t hold it on your behalf.
| Platform | Type | Best for | Self-custody |
|---|---|---|---|
| Abarai | Crypto ramp | Simple buying, direct to wallet | ✓ Direct |
| Kraken | Exchange | Active trading, MiCA licensed | On withdrawal |
| Coinbase | Exchange | Beginners, clean interface | On withdrawal |
| Binance | Exchange | Advanced traders, 350+ coins | On withdrawal |
Crypto fees — what you actually pay
Every crypto transaction involves at least two types of fees. It’s important to understand them before you buy:
1. Platform fee
Charged by the platform for the conversion service. Usually 1-5% for exchanges and 2-5% for ramps. Shown before you confirm — what you see is what you pay.
2. Network fee (gas fee)
Paid to the blockchain network for processing the transaction. Varies by network: TRC20 (~$0.50), BNB Chain (~$0.10), Ethereum (~$2-20+), Bitcoin (~$0.50-5+).
Practical example — buy $300 worth of USDT
Platform fee (~2%): ~$6
Network fee (TRC20): ~$0.50
Total fees: ~$6.50
You receive: ~$293.50 in USDT
Network fee (TRC20): ~$0.50
Total fees: ~$6.50
You receive: ~$293.50 in USDT
Tip to save on fees: For USDT, always choose the TRC20 network. The network fee is 30-40x lower than ERC20, and the transfer is just as fast. On a $500 transaction, you can save $10-15 just from network fee.
Scam warning signs — how to stay safe
Crypto scams are unfortunately common. Here are the most frequent red flags:
🚩 “Guaranteed returns”
No one can guarantee crypto returns. Anyone promising “100% profit” or “risk-free investment” is a scammer.
🚩 “Send crypto and receive double back”
Classic scam, often using fake celebrity accounts or cloned websites. Once you send crypto, it’s gone. Always.
🚩 Platforms without clear authorization
If you can’t find MiCA, FCA or FinCEN authorization, treat the platform with extreme caution. Also check if the domain has SSL (https://) and how long it’s been registered.
🚩 Unsolicited messages on WhatsApp or Telegram
Legitimate platforms don’t contact you out of nowhere to “invite” you to invest. Ignore unsolicited messages and block suspicious contacts.
🚩 “Support” asking for your seed phrase
No legitimate support will ever ask for your seed phrase, private key or wallet password. If anyone asks — it’s a scam.
Common mistakes beginners make
❌ Wrong network
Sending USDT on ERC20 to a TRC20 address — or vice versa — can result in permanent loss of funds. Always double-check the network before confirming.
❌ Photographing the seed phrase
Photos sync to cloud, can be accessed by apps, or stolen. Write the seed phrase on physical paper and keep it somewhere safe. Never digitally.
❌ Leaving crypto on exchange long-term
Convenient for active trading but risky for storage. If you don’t trade frequently, withdraw to your personal wallet. This is what the FTX collapse taught us.
⚠️ Investing more than you can afford to lose
Crypto is volatile. Bitcoin has dropped 70-80% multiple times in its history. Only invest money you genuinely won’t need for the next 3-5 years.
⚠️ Buying based on social media recommendations
Influencers are often paid to promote projects. Do your own research before investing in a coin just because it’s trending on Twitter or TikTok.
Frequently asked questions
Do I need to buy a whole Bitcoin?
No. Bitcoin is divisible into 100 million smaller units called satoshis. You can buy any fraction — $10, $50 or $1,000 worth — depending on your budget and goals. The same applies to all cryptocurrencies.
Do I need an account to buy crypto?
Not necessarily. On non-custodial platforms (crypto ramps) you can buy for small amounts without creating an account. For larger amounts, a quick identity verification is required — a photo of your ID and a selfie. This is a legal requirement under EU regulations, done once.
How long does it take to receive crypto after buying?
Depends on the blockchain. USDT TRC20, XRP and Solana: seconds to minutes. Bitcoin: 10-60 minutes. Ethereum: 1-5 minutes. Confirmation time can increase when the network is congested.
Is buying crypto legal?
Yes, in Romania and across the EU. Cryptocurrency is regulated under the MiCA regulation since December 2024. Buying, holding and selling crypto is completely legal. Profits are taxable — at 10% in Romania.
Can I lose all my money buying crypto?
Yes — especially with small-cap or speculative coins. Bitcoin and Ethereum are more established but still volatile, with price drops of 70-80% in bear markets. Never invest more than you can afford to lose, and always store funds in a personal wallet.
What’s the difference between a crypto ramp and an exchange?
A crypto ramp converts your money directly to crypto and sends it to your wallet — simple, no account needed. An exchange is a full trading platform with order books, charts and multiple pairs — more complex, funds stay on the platform until you withdraw.
Do I pay tax when I buy crypto?
Buying itself is not taxable. You pay tax only when you sell at a profit — in Romania, a flat 10% on gains. Read our complete crypto tax guide for more details.
What is the minimum amount to buy crypto?
Typically between $10-20 depending on the platform. Keep in mind that for very small amounts, network fees can eat a significant percentage of your transaction — so it’s more efficient to buy at least $50-100 at a time.
Ready to buy your first crypto?
No account required for small amounts. Crypto goes directly to your wallet. Available in 160+ countries.
