Blockchain technology is the modern day representation of the Mythical Hydra. Cut off one of it's heads, and two more take it's place.

Unlike the Hydra, Bitcoin and other cryptocurrencies have an infinite number of heads, and can be located anywhere, at any time, physically or through VPN.

The only thing that will go down eventually is the price, as capital moves into actual companies that utilize blockchain technology, having built on the recipes that are proven to work during this time period we live in now. Those companies themselves won't even have to touch fiat money, ever, but regulation will happen in some form. Can't stop the mob from taking it's cut, at least without becoming a mob too.
