Brain Wallet
A wallet whose key is generated from a phrase you memorise, which is risky because people choose guessable phrases.
A brain wallet turns a password or phrase you remember into a private key. Nothing is written down; the wallet lives in your head. It sounds like the ultimate hiding place.
In practice it's a trap. Humans pick phrases from songs, books and famous quotes, and attackers run programs that try billions of those every second. Weak brain wallets have been emptied within moments of receiving coins. And if your memory slips, the coins are gone for good. Modern wallets use a randomly generated seed phrase instead, which is far harder to guess.
Using a favourite lyric or quote as a wallet phrase. If it's memorable to you, it's probably on an attacker's list.
