Bitcoin was never anonymous.  Anybody who said it is, was stupid or lying.  Anybody who thought it is, may be in for a rude shock with unknown timing.  The notion that “Bitcoin is anonymous” is a persistent, pernicious myth.  It’s a global ledger, wherein each copy of the blockchain shows in full all transactions ever made.  What is so hard to understand about this?


They have been, for awhile.  But things develop slowly in Bitcoin.  They can’t just smack on a new feature, at risk of accidentally dropping a billion dollars worth of coins on the floor.
