Before buying any cryptocurrency: set up a self-custody wallet, learn what a seed phrase is and how to store it, decide on an exchange with fiat support, understand that crypto is volatile and you can lose your entire investment, know your tax obligations, and never invest money you need for rent or emergencies. This checklist covers each step in order.
Before You Buy Your First Crypto (Checklist)
4 min read
The short version
Buying crypto takes about 20 minutes. Being prepared to buy crypto responsibly takes about an hour of reading. This checklist is that hour condensed into the steps that actually matter, in the order that prevents the most common expensive mistakes new buyers make.
How It Works
The checklist, step by step. Step 1: Decide how much you can afford to lose entirely. Not how much can I invest but if this went to zero tomorrow, would my life be fine? That number is your maximum. Step 2: Choose an exchange with fiat support in your country. US: Coinbase, Kraken, or Gemini (all regulated, insured USD balances). UK: Kraken, Coinbase. EU: Kraken, Bitstamp. Verify the exchange is licensed in your jurisdiction. Step 3: Complete identity verification (KYC). Have government ID and proof of address ready. This takes 5 minutes to 3 days depending on the exchange and your documents. Step 4: Set up a self-custody wallet before buying. Download MetaMask (for Ethereum/L2s) or BlueWallet (for Bitcoin). Write down the seed phrase on paper. Never photograph it, never type it into any website, never store it digitally. Step 5: Make your first purchase. Start small ($50-$200) to learn the process before committing larger amounts. Buy Bitcoin or Ethereum (not altcoins) for your first purchase. Step 6: Withdraw to your own wallet. Do not leave crypto on the exchange long-term. Send your purchase to the wallet address from Step 4. Verify with a small test transaction first. Step 7: Understand your tax obligations. In most countries, selling or swapping crypto is a taxable event. Keep records of every purchase date and price from day one. Step 8: Set a plan and do not check the price hourly. Decide in advance: I will buy $X per month and not sell for Y years. Reactionary trading based on daily price movements is how most beginners lose money.
First $200 purchase, start to finish
Monday: Download MetaMask on your phone. Write down the 12-word seed phrase on paper. Store paper in a drawer separate from your phone. Tuesday: Sign up on Coinbase. Complete KYC (driver license photo + selfie, approved in 10 minutes). Link bank account via Plaid. Wednesday: Deposit $200 via ACH (free, settles in 3-5 days). Or use debit card ($200 instant, $6 fee). Buy $200 of Bitcoin. Coinbase fee: ~$3 (use Coinbase Advanced for lower fees). Wednesday evening: Withdraw Bitcoin to your own wallet. Go to Send on Coinbase, paste your BlueWallet receive address. Send a test of $20 first. Verify it arrives. Send the remaining $180. Total cost: ~$5-9 in fees. Total time: 30 minutes of active work across 3 days. You now hold $200 of Bitcoin in self-custody that no exchange failure can touch.
What People Get Wrong
You need thousands of dollars to start
You can buy $10 of Bitcoin. Most exchanges have no minimum or a $1-$10 minimum. Starting small ($50-$200) is actually the smart approach because you learn the process (buying, transferring, storing) without meaningful financial risk if you make a mistake.
You should buy whatever coin is trending
For your first purchase, buy Bitcoin or Ethereum only. They have the longest track records, deepest liquidity, and clearest regulatory status. Exploring altcoins, memecoins, or DeFi tokens comes after you understand the basics. Many beginners lose their first crypto investment on trending tokens that crash 90%.
Keeping crypto on the exchange is fine
For small amounts you plan to trade soon, an exchange is acceptable. For anything you intend to hold long-term, self-custody (your own wallet) eliminates exchange insolvency risk. FTX, Celsius, Voyager, and Mt. Gox all failed and customers lost billions. Your wallet, your keys, your coins.

Questions People Also Ask
- What is the absolute minimum I should know before buying?
- Three things: (1) You can lose everything (crypto is volatile, treat it as high-risk). (2) Your seed phrase IS your money (lose it = lose funds, share it = funds stolen). (3) Selling or swapping triggers taxes in most countries (keep records from day one). Everything else you can learn as you go.
- Should I tell anyone I own crypto?
- Be cautious about broadcasting your holdings publicly. Crypto theft via social engineering (targeting known holders) is real. You do not need to keep it secret from close family, but advertising holdings on social media or to acquaintances creates risk. The $5 wrench attack (physical coercion) is a real threat model for known large holders.
- When is the best time to buy?
- Nobody can reliably time the market. Dollar-cost averaging (buying a fixed amount on a regular schedule regardless of price) removes the timing question entirely and has historically produced good results for long-term holders. The best time is whenever you have money you can afford to lose and have completed this checklist.
