After using this wallet for about 2 weeks, FULL-time, I highly doubt even Jack Dorsey would / could use / trust his own creation! The name, Bitkey was copied from a great BTC project around 2014! The hardware design is similar to some Crypto Wallet by a popular Korean company! So, we have this App which are the MOST critical - it can either make enough noise so more and more people would buy - OR break / limit the entire crypto experience for both old or new fans! Sadly, this App is as useless as your imagination allows! Once you get things up and running which impressively takes just a few minutes even for newbies - then that’s the end of usefulness of this super expensive BTC only Wallet! There is no screen to confirm your transactions - you depend and count on this App which could and would be easily hacked! Next? You cannot create more than 1 BTC wallet. Just ONE! For the love of Satoshi, this multi-wallet has been the most basic feature of each and every crypto world since forever! More? You cannot factory reset this thing - at least not an obvious / easy way. Their super short and limited tech documentations show nothing! Although they keep saying it’s designed for newbies - highly unlikely newbies would find this wallet useful. I could certainly write a book about all limitations of this wallet but space is limited - for now, however, Bitkey is using early adapters as their mouse lab to test this App! I recommend this wallet for mini hockey fans only!
