1. What is a crypto wallet?
A wallet lets you send and receive cryptocurrencies such as bitcoin. Despite its name, it does not really contain your bitcoin: the coins are recorded on the blockchain. The wallet holds your private keys The secret that proves some bitcoin belongs to you and lets you spend it. Your wallet keeps it; the recovery phrase can rebuild it., a kind of very complex password that proves you own the coins and lets you spend them.
When you create it, it gives you a recovery phrase The 12 or 24 words a wallet gives you when it is created: they rebuild your keys on another device. Whoever has them has your bitcoin: never give them to anyone. 5 mistakes to avoid of 12 or 24 words, which can rebuild those keys on another device. Whoever has those words has your funds: it is beginner mistake number 1.
There are two main families: hot wallets A wallet connected to the internet: app, software or extension. Handy day to day, but more exposed to attacks. Hot, cold or hardware?, connected to the internet, and cold wallets A wallet that keeps its keys offline: safer for large amounts, less practical for frequent payments., kept offline. An exchange account, on the other hand, is not your wallet: the exchange holds the keys.
2. Hot wallets: handy, but connected
A hot wallet is connected to the internet. It is the most convenient option for quick or everyday transactions. It comes in three forms:
a mobile appdesktop softwarea browser extension or a specialised websiteThe pros: easy to set up, ideal for trading or paying day to day, reachable anywhere over the internet.
The cons: more exposed to online attacks, malware and phishing, and less suited to large amounts.
Example: you buy crypto regularly and sell it within the month? A hot wallet makes life easier. Only download it from the official website or app store, checking the publisher: fake apps imitate the real ones.
3. Cold wallets: offline and safer
A cold wallet keeps the keys offline, with no internet connection. That includes:
keys printed or written on papera dedicated device, covered just belowa computer that never goes onlineThe pros: with no connection, the risk of remote hacking drops sharply. Ideal for keeping large amounts over the long term.
The cons: much less practical for frequent transactions, and a risk of physical loss (paper misplaced, drive damaged).
Example: you have put a large sum into bitcoin and do not plan to touch it for several years? A cold wallet is a very good solution.
Be careful with old-style paper wallets, a private key printed from a website: they are discouraged today, because the site generating the key could keep it, and spending part of the balance without a mistake is tricky. Paper is better used to write down a hardware wallet’s recovery phrase.
4. Hardware wallets: the best compromise
Hardware wallets are a particular kind of cold wallet: small devices, often the size of a USB stick, such as those made by Ledger or Trezor.
- Your private keys never leave the device: transactions are signed on it directly. Even if your computer is hacked, the keys stay protected, provided you check the address and the amount on the device’s screen before approving.
- The best balance between security and convenience: you plug it in only to approve a transaction, then unplug it. Well suited to people who hold their crypto for a long time (“HODLers”).
- Unplugged, it is a cold wallet. Plugged in, it is almost as easy to use as a hot wallet, but the keys stay inside the device.
The cons: an upfront cost, often €70 to €150 for common models, and a slightly more technical setup for beginners.
Buy it new, from the brand’s official store or an authorised reseller, never second-hand, and refuse any device delivered with a recovery phrase already written down: you must generate it yourself. Even an authorised reseller can be the weak link: what the CryptoBilis case taught us.
5. Which one to choose?
It all depends on how you use it and how much you hold:
a hot wallet, with small amountsa hardware wallet, or another cold walleta small part in a hot wallet for everyday use, the rest kept coldCombining the two is very common. In short: the hot wallet for flexibility and quick transactions, the cold wallet for maximum long-term security, and the hardware wallet that brings both together while staying very safe.
6. For miners: which address to give the pool?
In solo mining, on FindMyBlock as on any pool A server that machines connect to. A regular pool shares the earnings, a solo pool does not. Solo or pool?, the address you enter in the machine is the one that will receive the block if you find it. So it must come from a wallet whose keys you hold, never from an exchange: a block reward is a special kind of transaction that not every exchange handles.
A hardware wallet works very well: receiving needs no signature, so the device can stay in a drawer. Display the receiving address on its screen to check it matches the one you copy. Step-by-step settings: solo mining on FindMyBlock. And the day your machine finds a block: what happens next, all the way to taxes.
