Bitcoin is no more dirtied by criminals than gold was dirtied by criminals, or fiat currency was dirtied by criminals. Bitcoin can't be easily controlled by regulation. That is what scares them. I'm not scared for the banking industry, I despise it and there's not much that would make me happier then to see the entire Banking industry go under and every greedy piece of human feces who took part in it, LOSE EVERYTHING THEY STOLE through fractional reserve banking. They should be banished from the planet. Banks biggest weakness is operational inefficiency and huge overheads. Time to start cryptocurrency based financial institutions ,lending ,accepting deposits. Financing renewable energy & e-automobiles. I belive that if the U.S. government, banks or any other government were really smart they would roll their fiat currency over into Bitcoin and then happily watch as all of their government debt magically dissolved.
