The blockchain was designed to keep their grubby mitts off. It's up to the exchanges to resist governmental encroachment at their end, and up to us to build an internet economy outside their control on ours.
Call out the quislings who support government control schemes, and resist the busybody control freaks!
I fear that's why "they" haven't squashed Crypto yet. They want to assimilate it into their current system of enslavement. Once governments start making their currencies on the block chain they will then declare all other Crypto to be illegal. The question is, will we nullify them by creating our own economies or will we capitulate and keep doing business as usual.
