Call me dumb but i don't get the hologram/private key thing...
If the coin holds the private key, what prevents someone from reading it, sell the coin, and move the BTC away after it's sold? :-/
Can someone explain please?
They would have to destructively tear off the hologram to read the key. These holograms tear in a tamper evident pattern.
D'Oh...now i get it. The hologram is a sticker and covers the private key... i had some sort of hologram directly lasered on the coin's surface in my mind...you know, to make it look pretty
