The people who fund domestic terrorism don’t exactly hide what they are doing. They don’t need to use crypto. They are protected. They can concoct a coup against the President or burn cities ... Nothing happens to them. Crypto? That’s for little people.

Blockchain will eventually be omnipresent. The only problem right now is comprehension and IT implementation capability.
