There’s been a lot of speculation on this tx.

Everything from wondering if it’s a 51% attack, not believing it was a single tx, thinking is’s a 2btc fee and not 20.

But to me, this points to someone that didn’t follow their normal routine, was in a hurry, etc.

Sorry this happened whoever they are, but you have to have good operational controls when you’re moving anything significant, with no deviations.
