How to BuyCryptofor the First Time: 5 Steps with Real Numbers
Five steps from cash in your bank account to crypto in your own wallet: pick an exchange, complete identity verification, fund the account, place your first order, then withdraw to a wallet you control. The whole thing takes 30 to 60 minutes the first time and 2 minutes after that. The hero below shows what your first 100 USD actually buys you on each major exchange.

Section 01 · Where to buy
Three places you can buy crypto
For a first purchase, only one of these makes sense. Centralized exchange is the default and the right answer for 95% of beginners. The other two exist for specific use cases - they are useful to know, but not where you start.
Centralized exchange
What it is
Binance, MEXC, Bybit, OKX. App or website, bank card or transfer in.
Best for
First buy, ongoing trading, all common coins.
Caveat
Requires KYC. Move coins to your own wallet after buying.
P2P market
What it is
Direct trades with other users, escrow handled by exchange. Binance P2P, Bybit P2P.
Best for
Regions where bank cards do not work for crypto. Local payment methods.
Caveat
Higher friction. Choose sellers with 1000+ orders and 99%+ rating only.
DEX
What it is
Decentralized exchange. Uniswap, Jupiter. Trade directly from a wallet.
Best for
Buying small altcoins not listed on major exchanges. Already-on-chain.
Caveat
You need crypto already. Cannot buy with bank card directly. Skip for first buy.
Section 02 · Pick exchange
Picking your first exchange
For the first purchase, the differences between major exchanges are smaller than they look. All charge around 0.1% on spot trades. All accept bank cards with a 1.5 to 2% fee. All require KYC. The decision is mostly about availability in your country and which app you find friendlier.
Recommendations by use case: MEXC for the lowest fees and 2,000+ coins, accepts no-KYC small purchases. Binance for the deepest liquidity and most learning content. Bybit for the smoothest mobile app. OKX for advanced features once you are past the first trade. Full breakdown in our crypto exchange comparison.
Binance
Largest exchange. Best liquidity, most coins, simplest buy flow.
Three things to do before depositing money. None of them is optional.
01
Sign up with a real email
Use an email you control long-term. Do not reuse a password from any other site. The exchange password should be unique and stored in a password manager.
02
Enable 2FA immediately
Use an authenticator app (Google Authenticator, Authy) - never SMS 2FA. SIM swap attacks bypass SMS in minutes. Save the 2FA backup codes somewhere physical.
03
Complete KYC
Upload a passport or ID + take a selfie. Approval takes 5 to 30 minutes on most exchanges. Without KYC most exchanges block withdrawals - which means your coins are stuck on the platform.
Section 04 · Funding
Funding the account
Three common methods, ranked by fees from lowest to highest.
Bank transfer (SEPA / wire / domestic). Lowest fees - usually free or under 1 USD. Takes 1 to 2 business days. The right choice for amounts above 200 USD if you are not in a hurry.
Bank card (Visa / Mastercard). Fee 1.5 to 3% on top of the spot fee. Instant. Use it for the first purchase to learn the flow, then switch to bank transfer for larger amounts. Avoid third-party widgets labeled MoonPay, Simplex, Banxa - they charge 3 to 5% on top.
P2P market. Buy USDT from other users with local payment (Wise, Revolut, bank apps). Often cheapest in regions where direct deposit is restricted. Filter sellers with 1,000+ completed orders and 99%+ approval. Never release the crypto before the payment shows in your bank.
Section 05 · First buy
Making your first purchase
Two ways to buy on the spot market. The first is faster, the second saves money.
A
Market order (instant, slightly worse price)
Pick the trading pair (BTC/USDT). Click Market. Type amount in USDT. Click Buy. Done in 2 seconds. You pay the current best ask price plus 0.1% fee. Use this for the first ever buy - the simplicity is worth the tiny extra cost.
B
Limit order (set your price, wait for fill)
Same screen, click Limit. Set a price below the current ask (say, 0.5% lower). Click Buy. Order sits in the book until price reaches it. Maker fee is often 0% to 0.05% versus 0.1% for market - meaningful on larger amounts.
Section 06 · Withdraw
Move it to your own wallet
The single most important step that beginners skip. "Not your keys, not your coins" - if it is on the exchange, the exchange owns it. Withdrawal is required to actually own what you bought.
For first amounts under 500 USD, a hot wallet on your phone is fine (Trust Wallet, Phantom for Solana). For larger amounts, a hardware wallet like Ledger or Trezor. Detailed setup in our guide on how to store crypto safely.
Process: copy the wallet address from your wallet app, paste into Withdraw on the exchange, choose the right network (BTC for Bitcoin, ERC-20 for Ethereum tokens), send a small test amount first, confirm it arrived, then send the rest. Withdrawal fee is typically 1 to 5 USD depending on coin and network.
Section 07 · Mistakes
Four mistakes that cost beginners money
01
Wrong network on withdrawal
Sending USDT on ERC-20 network to a TRC-20 address. Funds vanish forever - the address looks valid but cannot be unlocked. Always match the network on both sides.
Test with 5 USD first. Always.
02
Buying through MoonPay/Simplex widgets
The big "Buy with card" button on many exchange home pages routes through a third-party widget that charges 3 to 5% extra. The actual exchange spot market charges 1/10 of that.
Deposit funds first, then trade on the spot market.
03
Leaving everything on the exchange
"I will move it later." Months later FTX-style event happens. Funds you do not control are at someone else's mercy. Move at least the long-term portion to your own wallet.
Withdraw to wallet within a week of buying.
04
Buying based on Telegram tips
First-purchase money should go into BTC or ETH, not whatever a Telegram channel pumped today. Learn the platform with a major coin first. Altcoin gambling can wait.
First three buys: BTC and ETH only.
