Self-custody wallets are the gold standard for securely storing Bitcoin, offering unparalleled security and control. As Bitcoin advocate Andreas Antonopoulos famously said, “Not your keys, not your coins.” While centralized exchanges (CEXs) like Coinbase and Binance drove early adoption, they hold users’ private keys—a critical security risk. Today, non-custodial (self-custody) wallets have surged in popularity. This guide explores their benefits, types, and step-by-step usage.
