so we are still growing hash rate but we are yet to get to the 114.16 we were from feb 9 to feb 23
still 113.76 is nothing to sneeze at
Theoretically, given that the value of bitcoin is lower, we should expect to see a decline in difficulty, with the machines being shut down. Or am I wrong in this reasoning?
Well, the numbers prove that I am.

good old usa tax laws and really big investment. marathon has over 300 containers with 300 units in each one.
so 300 x 270 = 81,000 th in each container x 300 = 24,300,000 th that is 24,300 ph or 24.3eh about 3% of the network in just 1 location.
So if they simply switched from s21 to s21xp
they went from 18 eh to 24.3 eh a 6.3 eh gain which is just a bit under 1% gain for the network.
A lot of big companies are simply switching from s21 to s21xp
so 200 to 270 means a 14% increase in hashrate.
these companies are not paying 7100 a machine they get better prices
and they get around a 33% tax break for the upgrade
