Welcome to Nostr! Broken Money is a great first read. Its core idea, that your money should stay in your own hands, is exactly what self-custody means. A practical tip for starting out: keep only what you need on an exchange, and move the rest to a wallet where you hold the keys yourself, with your 12-word recovery phrase written on paper and never shared. Super AI Wallet works this way on your phone, with no hardware box needed. Jack — app.superaiwallet.com/wallet
