I don't care how much regulation you throw at them. If you let them bitcoins in custody we'll have one billion bitcoins in circulation before a year. They simply can't be trusted.
Thats not possible; Banks can't just create more bitcoins, just like a bank can not produce more gold or simply issue more stocks of a certain company. (that is the beauty of the Bitcoin)
actually, if banks did hold bitcoins as a financial product they offer. it wouldnt be to much of a stretch for them to try off-chain transactions.
by giving people a SQL bank database balance of bitcoins and let people trade the database (leading to fractional reserving) where there are only 21million real bitcoins, but the banks showing 1billion bitcoins on their SQL database..
... just like the current FIAT debt crisis
... just like karpals let people trade his SQL database while hiding the real coins.
sounds almost like we will be screwed either way.... no ethics left anymore....
