The absolute worst coin you could trade if you didn't want governments to pay attention to you is
DRK
Don't kid yourself that regulators give a damn about whether cryptos have transparent blockchains or not

Look, all regulators need (look for) is an excuse. Anonymity is the perfect excuse.
Up till now, regulators in the US have been pro-bitcoin because law enforcement tells them that transactional crime in crypto is actually easier to track due to the leger.
DRK is a different story and can be used as a sound bite or a example of the "crackdown" if it comes.
Politics = perception = reality.
