This is why Poloniex sold-out to Circle. Unfortunately, any exchange in the USA is a target at this point.
It was largely expected that the regulators would go after the exchanges, but it was the mistake of the whole cryptocurrency community to rely on these centralized trading venues.
Either crypto disconnects from fiat, or crypto becomes dependent on fiat, and by extension the very system crypto was designed to replace!
That's a good way to thin about it, for sure. We need to get serious about agorism and using a completely alternative system for exchange outside of fiat. Stuff like this will hopefully just accelerate the inevitable. At the same time, people need to level up their personal online security so they can take personal responsibility for securing their assets. People need to be adults.
