Re: The banks don't like bitcoin.
" Bitcoin is used in criminal transactions and money laundering. Not all certainly but to a large enough degree that this makes sense."
Bollocks. By your own reasoning, then even if all bitcoin transactions where criminal, then it's a minute part of the banking system. Thus the majority of criminal financial activity must be within the current financial system.
The same investment vehicles and corporate structures that are used by the "legitimate" banking system are used by criminals, money launderers and tax dodgers. Are there going to be a crackdown on those? Don't be daft, there's proper money and power in there.
