21bitcoin Save Wallet

We recommend keeping your coins in self custody, and while 21bitcoin offers a convenient built-in wallet for storing Bitcoins, it is custodial in nature, which means you don't have full ownership of the coins.

However, on 21bitcoin you can also easily transfer your Bitcoins to a non-custodial wallet of your own.

Hardware wallets offer superior cold storage solutions for your cryptocurrency compared to simple software hot wallets. Among the top hardware wallets for cold storage is the Trezor Model T, created by SatoshiLabs, pioneers in the bitcoin industry.

One of the remarkable features of the Trezor Model T is that the seed phrase is never entered on any computer. Instead, it is displayed once on the color touchscreen during the wallet's setup, allowing you to write it down on the seed phrase backup card and keep it offline, always.
