Not even a little.

This is a hilarious blunder. The whole point of Cryptonian currencies is to evade hegemonies. They can impact the currencies, sure, but the price efficiency will cripple their ability to respond.

The costs of chasing down those who allegedly tax evade will far far far outweigh the economic damage that they cost. The only way this can damage CC is if every bank in every country and every government puts aside their differences and works together. And that's not possible. The one redeeming factor of tyrants is that they don't play well with others. It's gonna be backstabapolooza.
