Are you thinking of something to compete with Nano Ledger and Trezor?
I've always wondered whether some sort of hard wallet within a banks security vault would be of interest. I cant imagine its comfortable potentially having millions of dollars worth of crypto on stick in your house. Maybe it would be nicer, if you could store a ledger in some sort of security vault that you can access remotely.
It would have to be cold storage unless you were using it though, otherwise whats the point?
I'm not sure how it should be marketed yet, which is why I'm all-in with the idea of getting good feedback from the community. How does the community imagine it being used?
And yes, it is a crypto storage device. It's a quite simple device actually, and it's non-electronic. I think if it was marketed the correct way it can get a lot of traction. Stay tuned, I will post a detailed explanation within the next few days!
