Crypto Wallets

How to safely store your crypto: hot wallets, cold wallets, and best security practices.

Types of Cryptocurrency Wallets

A cryptocurrency wallet does not store the cryptocurrencies themselves (these are always on the blockchain). It stores your private keys (secret codes that allow you to control your funds).

📱 Hot Wallets (online wallets): • MetaMask: the most popular Ethereum wallet, works as a browser extension • Trust Wallet: mobile multi-chain wallet • Phantom: for the Solana network • Coinbase Wallet: from the Coinbase exchange

✅ Pros: convenient, quick access ❌ Cons: susceptible to hacking attacks

🔐 Cold Wallets (offline wallets): • Ledger Nano S/X: the most popular hardware wallet • Trezor: the first hardware wallet on the market • BitBox: Swiss hardware wallet

✅ Pros: highest level of security ❌ Cons: more expensive, less convenient for daily use
