Bulgaria is currently sitting on one of the biggest stashes of Bitcoin in the world. How did the European nation come into the possession of this enormous sum of money? A crackdown on organized crime by the Bulgarian law enforcement in May 2017 resulted in the seizure of a stash of 213,519 Bitcoins, enough to pay off a quarter of the country’s national debt.
