I dont think AMD and Nvidia will allow to pow die

do you think they dont count money? Miners are most profitable customers in GPU industry and all GPU history. They did fortune on miners

))) i dont think they will let go valuble customers like miners. Gamers yes but they not profitable as miners so dont worry guys we are valubale customers

1. Nvidia do not want miners buying their cards! Why do you think they started making cards only LHR?
2. There is nothing Nvidia or AMD can do to stop POW even if they wanted to (but actually they don't. See point 1)
