During the last week or so the Hashing power x13 has jumped from a normal 2.5 TH/s to at times 5 TH/s on Nicehash. That has never happened before, even at high price when all where in, it never exceeded 3 TH/s.

I don't think that 2 TH/s X13 hashing power has suddenly been available, and joined NH.

It is more likely that some large mining operator has cracked the overclocking  on the giants.

Or am I overlooking something ?

Anyone know something ?
