Spiking...did Saylor (or someone even bigger

) buy a massive amount?
It happened without any change to stock market futures-something bitcoin specific?
As someone else suggested, tax selling now over. Could be people trying to front-run tomorrow.
Well, tax selling was over early-mid last week, but it could be a delayed effect, sure.
EDIT: not that I care much about gold, but both gold and bitcoin are up in a similar % range today while stock market futures are down a bit (less than 1%, though).
