Isn't this initiative rather dangerous. I mean, walking around woth your cold wallet on you. That's like telling a whole bunch of people you meet wherever you go that hey look, I have cash on me and I've got it all on my hand. Anyways even if someone can't use it after stealing, it is still dangerous walking around telling people you have money.
Even if not telling about it, the user will surely be robbed by having it on their wrist as once this comes out, those who're in the muse of fetching it all away from the user will become alert and do whatever they can (at their local premises only as they already know about the watch now) to rob you and suck out even the last drop of your whole crypto savings. I believe there is one project where the devs are developing something like a chip that can be installed in our hand and we can use our wallet through our eyes being scanned and what not. If that becomes possible, I don't see any reason as to why people would go for such things that could be life-threatening to them.
