Check out Opendime (the Bitcoin Stick). Their product makes Bitcoin gifts/transfers trust-less, because the private key is generated on the stick and is not known/revealed to anyone until the stick is physically modified in order to spend funds – this is accomplished by punching a hole at the designated location on the current gen stick, or for the previous gen stick pushing out the middle portion of the stick. Once funds are spent, the stick should be discarded; The intent is to load it once, and spend it once. I’ve only recently discovered Opendime, thanks to crypto twitter, and after looking into it the product sounds great. If you try it, drop a note with your thoughts. I plan to order a couple as well.
