We understand the bitcoin community is seeing more Bitkey content in your algorithm. While our team is flattered, this is not a "psyop." We have not changed our marketing in recent weeks. However, current events have led to many new people discovering, using, and discussing Bitkey as a solution to several common self-custody problems. We will continue to help securely store your bitcoin as we have for years. We also reserve the right to tell people what we have built, what we are going to build, and why. To our longtime customers, those who have just joined us, and those still exploring self-custody solutions, our team appreciates all your questions and comments. Please keep the feedback coming.

Always aiming to improve the experience.
when i got the beta Bitkey, i started using it right away then my dad's bitcoin stack grew to the point where self custody made sense for him, so i handed it to him, since it was super easy to use and secure then i got a second Bitkey and created a new account on a different phone for my own stack then i got a third Bitkey, at this point i'm basically a hardware wallet hoarder but i have nowhere left to create an account right now, each Bitkey account needs its own phone soon you'll be able to have multiple accounts on one phone, which will make it easier to manage my ₿ and my family's without also hoarding phones
