Bitcoin wallets are essential tools for managing your cryptocurrency securely. Unlike traditional wallets, they don’t store physical coins but safeguard your private keys—the cryptographic credentials needed to access and transact with your Bitcoin. Understanding the various wallet types ensures you choose the right balance of security, convenience, and control.

Custodianship: Custodial vs. Non-Custodial Wallets
Custodial Wallets
