In our last guides, we covered what Bitcoin and cryptocurrency are. Now the practical question: where do you actually keep it? The answer is a crypto wallet. But a crypto wallet isn't what you think — let's break it down.
It's not a wallet like in your pocket
A crypto wallet doesn't "hold" your coins the way a leather wallet holds cash. Your crypto actually lives on the blockchain (that shared record we talked about). What the wallet holds are your keys — two special codes:
- Public key: like your email address. You share it so people can send you crypto.
- Private key: like your password. Whoever has it controls your crypto. Never share it with anyone. Ever.
Think of it this way: the blockchain is a giant safe-deposit building. Your wallet is the key ring that opens your box.
The two big types (keep this simple)
1. Hot wallets — connected to the internet. These are apps on your phone or computer (like Trust Wallet, Exodus, or the wallet inside an exchange app). They're convenient — great for small amounts and everyday use. The tradeoff: because they're online, they're more exposed to hackers.
2. Cold wallets — offline. These are physical devices (like a Ledger or Trezor) that look like USB sticks. They stay offline, so hackers can't reach them. Best for larger amounts you plan to hold long-term. The tradeoff: they cost money ($50–$150) and take a bit more learning.
Rule of thumb: small spending money → hot wallet. Serious savings → cold wallet.
Custodial vs. non-custodial (one more distinction)
- Custodial: someone else holds your keys for you (like keeping money in a bank). Easier — you can reset your password. But you're trusting a company.
- Non-custodial: YOU hold your keys. Full control, full responsibility. Lose your keys, lose your crypto.
For beginners, starting custodial (a reputable exchange) is fine while you learn. Move to non-custodial when you're comfortable — that's real ownership.
The seed phrase — the most important thing in this guide
When you create a non-custodial wallet, it gives you 12 or 24 random words. This is your seed phrase — the master backup of everything.
- Write it on paper. Not in your phone notes, not in an email, not as a screenshot. Paper, stored somewhere safe. (You already know my feelings about paper.)
- Never type it into a website that you didn't open yourself from the official source.
- Anyone who asks for your seed phrase is robbing you. No exceptions. Not "support," not "verification," not anyone.
How to choose your first wallet
- Start free and simple: a well-known hot wallet app with good reviews.
- Check it's real: download only from the official website or your phone's official app store. Fake wallet apps are a top scam.
- Turn on every security option: PIN, biometrics, two-factor authentication.
- Start tiny: move a very small amount first. Make sure you can send and receive before trusting it with more.
Red flags to avoid
- Wallets you've never heard of, promoted by strangers online.
- Anyone offering to "set up your wallet for you."
- Apps that ask for your seed phrase "to sync" or "to verify."

Your keys, your crypto. Guard them like they matter — because they do.
Legal note: This article is for education only — not financial, tax, or legal advice. Crypto laws differ by country and change often. In the United States, the IRS treats cryptocurrency as property, so selling, trading, or spending it can trigger taxes, and new rules (like the 2025 GENIUS Act on stablecoins) keep evolving. In Haiti, there is currently no specific crypto law: it is not banned, but it is not officially recognized either — only the gourde is legal tender — so you operate without a regulatory safety net. Always check current local rules before buying, selling, or earning crypto, and talk to a qualified professional about your situation.
