Yeah  some will mine to a fresh address hoping to beat taxes.
So buying 10 s17+ at 1567 each does not worry them.
I do think  most of this jump is bitmain cycling out some lessor gear and dropping in better gear. Or maybe a big farm went online.
A 6% jump is about 7eh
9         s19pros = 1ph
90       s19pros = 10 ph
900     s19pros = 100 ph
9000   s19pros =  1    eh
63000 s19pros =  7    eh

63,000 x 3.3kw = 207900kw or  207.9 megawatts.

This is a lot of gear.  I know a plant was being built in Canada it was supposed to do 300 megawatts.  Maybe  they went on line.
