No cost, no sign-up, no catch. Start at the top if you're brand new, or jump to whatever you're stuck on.
The basics
What cryptocurrency actually is
Cryptocurrency is a virtual medium for exchanging money. It uses cryptography and blockchain technology to move value online, without a bank sitting in the middle taking a cut and deciding whether you're allowed.
Cryptocurrencies are decentralised — no single entity controls them. In theory that puts them beyond government control, though governments have been working hard on regulating them and that picture keeps changing.
The practical upside for you: you can send money to another person, anywhere, with very few processing fees and without asking anyone's permission. That's the part that made me pay attention, and it's the part that still matters.
Step by step
How to buy your first coin
Five steps in order. Don't skip the first one — it's the only one that's genuinely urgent.
Set up 2-factor authentication before anything else
Download Authy or Google Authenticator first. Most exchanges — Binance included — now require 2FA before you can even finish signing up, and your wallets will want it too. Doing this first saves you a frustrating hour later.
Choose an exchange
An exchange is where you go to buy and swap cryptocurrencies. There are hundreds; the ones I've actually used are Binance, Kraken, KuCoin and Gate.io. You can buy with a credit card, debit card or wire transfer.
You don't need a lot of money to start. You can buy fractions of a coin — a few dollars of Bitcoin is a perfectly sensible first purchase, and a much better teacher than reading about it.
Choose what to buy
There are thousands of coins. Start with the ones that have been around long enough to have a track record — Bitcoin, Ethereum, Litecoin, Ripple. The exotic stuff can wait until you understand what you're looking at.
Move it into your own wallet
Coins left sitting on an exchange are not really yours — the exchange holds the keys. A software wallet like Trust Wallet is right for money you're actively using. A hardware wallet like Trezor is right for money you're holding long term and don't need to touch.
To be clear, because this trips people up: a phone wallet is fine for your spending money. What's unwise is keeping your life savings on a device you carry to the beach. Match the wallet to the amount.
Spread it out, and expect a rough ride
Don't put everything into one coin, the same way you wouldn't put a whole pension into one company. And prepare yourself for the swings — this market moves in a way that stock markets don't.
Don't invest more than you are willing to lose. Not "can afford to lose" — willing. Assume the worst case, and if that number keeps you up at night, make it smaller.
Choosing an exchange
What to look for, grouped by what matters most
There are eighteen things you could check. These are the five groups they fall into — and honestly, the first two decide it.
Can they keep it safe?
Cold storage for customer funds, mandatory 2FA, and regular independent security audits. Also check they comply with the rules where you live — KYC and anti-money-laundering requirements exist to protect you as much as anyone.
Can you actually get money in and out?
Check they support your currency and your country before you sign up — geographic restrictions catch people out constantly. Then check the deposit and withdrawal methods: bank transfer, card, digital wallet.
What does it cost?
Trading fees, withdrawal fees and deposit fees all eat into your money. High trading volume matters too — a busy exchange means you can sell without moving the price against yourself.
Does it have what you want to buy?
Check your coins are listed and the trading pairs you need exist — BTC/USD, ETH/BTC, and so on. No point joining an exchange that doesn't carry what you came for.
Will it treat you well?
An interface that suits your level, a working mobile app, responsive support when something goes wrong, and account recovery options for the day you lose your phone. Read real user reviews, not the marketing.
For business owners
Taking crypto payments in your shop
The Bitcoin Cash Register app installs and sets up in a few minutes. No sign-ups, no hidden costs — a quick, secure way to start accepting Bitcoin Cash payments at your business.
The detail that matters at a till: zero confirmations. The Bitcoin.com wallet supports them, which means your customer's payment lands instantly and their balance updates on the spot — no standing at the counter waiting.
Wallets and exchanges that don't support zero confirmations leave the payment pending until the blockchain confirms it. That's anywhere from ten to sixty minutes. Fine for a transfer, useless for a queue of customers.
