These look really cool. I question the security of them though. Most people will likely hold onto these for a long time. Theoretically couldn't a seller write down all of the hidden keys and cash them in at some point making the coins worthless?

Currently there is no way to make a physical btc without someone putting the private key inside. However these are put together by Casascius. He is a well known and trusted member on these forums. He has made a heck of a lot of them. Check out

I mean there could be an automated way TBH, it would not be that difficult to make it either.
However, on that note. I have actually gotten a few premade paper btc's, like bought them, I know I know. but I will say I never had a problem. It is essentially, to me at least, makes me wonder why would someone do that. Especially when there is SOOOO much more business to be had?
It is quite a foolish thing to do IMO. If you need a quick dollar, rob a vending machine, at least you know that will always be there. Hahah.
