Someone just moved 40000 Bitcoins. And the best part is the fee! LOL
Just imagine the paperwork you need to go through if you are going to move 400M USD from one account to another if you are going to use the banking system.
It looks like they've just moved their coins to a segwit address (the output address starts with a 3 which indicates segwit). Just some housekeeping here, nothing to see.
