Open-source wallets are great for transparency. Copay Wallet is fully open source, so anyone can audit its code on GitHub, and it’s user-friendly for managing BTC and BCH. You can download it at https://copaywallet.io for mobile, desktop, or web. Its HD feature enhances privacy with new addresses per transaction, and multisig adds security for shared wallets. BIP prevents sending to wrong addresses, and the interface is simple yet powerful with features like coin control. Definitely worth trying!
