This will probably end up in an ever-deepening split between regulated and unregulated markets. Exchanges and other services in countries like the US, particularly ones dealing with fiat, will be compelled to comply with regulations, full KYC, etc. Offshore / crypto-only services will still exist without KYC - I think there is a demand for that. Regulators and lawmakers don't really grasp the technology so they will simply squeeze the compliant entities as much as they can and declare others as outlaws/terrorists etc. Not sure whether sending crypto from one side to the other can be successfully restricted. You can put any coin through a mixer.
Now that you mention mixers, could you point out some that you think a legit and worthy?
