Security
The Coinkite Coldcard is one of the highest security hardware wallets on the market, using a Secure Element chip that encrypts its contents and is protected by a PIN code.

This wallet is an excellent option for Bitcoin holders looking to enhance their privacy and protect their investment. Since it only supports one cryptocurrency – Bitcoin – its compatibility reduces attack vectors relative to wallets with support for multiple coins. Furthermore, its Secure Element makes resetting devices nearly impossible without first entering password.
As soon as you first use your Coldcard, it will prompt you to create a PIN and backup plan. Next you will be given 24 seed words which serve as master backup and should be written down somewhere safe – should something happen to your Coldcard, these can help recover your bitcoin.
Another way to strengthen the security of a cold wallet is by adding a passphrase. This will prevent hackers from accessing it even if they manage to acquire your Seed Words, and can be done easily by going into Settings and selecting “Add Passphrase”. To do so, go into “Settings and add Passphrase”.
If you are serious about investing in cryptocurrency, a cold wallet should be at the top of your priority list. A cold wallet offers much greater protection than keeping digital assets on an untrustworthy computer or mobile device; just make sure it comes from a reputable brand like Coinkite and you purchase directly from its manufacturer instead of Amazon or other used sellers to ensure an authentic Coldcard is received.
