Then you could just print off several of these whenever you need to, and spend them at Bitcoin accepting institutions. JUST LIKE FIAT PAPER MONEY.
The seal on Paperwallets, so far as I have seen, was always a FAIL (just with varying afford to break it)
But you could do the following: Create a BANK. That prints out paper money in classical forms, with a serial number on it. And guarantes to print exactly the amount kept stored inside it's cold wallet. There is none such thing like a private key printed on them. Nothing to steal there, besides the note itself. As in classical money.
Why doing that, you might ask? Well, for several reasons.
- It is possible, so it will be done, period. Stop argueing.
- One can print nice pictures of historical ASIC devices on the front
- It reaches a "niche market" out there, where a currency is needed for simple trades. Wares vs. cash right on spot.
Thats not bitcoin then, how would one redeem their coins from the note other than physically taking it to this bank (would need locations everywhere )?
