I think the agencies may pick on those exchanges who comply more loosely with the KYC first. I am glad maidsafe are pursuing options outside of the US though.
If this is the sign of things to come, it could do more harm than good to the US econony. This is the current booming IT technology - the biggest since the dot com boom - and it would be foolish to attempt to repress it. They claimed in the hearing that they didn’t want to make dot com mistakes again, but what if those mistakes actually fed the success in the US?
As crypto is borderless I don’t think it will stop US citizens using foreign exchanges anyway. In the name of protecting them (or their financial institutions perhaps…), they will just throttle their share of the spoils.
