Another year has come and gone in the cryptocurrency industry, leaving behind an ocean of developments, drama, price swings and innovation — all moving at a breakneck pace that even Barry Allen would have a hard time keeping up with.

Twitter, of course, sat right in the middle of the action, with people and companies posting all sorts of industry-related content.
