You guys are totally and completely wrong. Bitcoin and altcoins will go parabolic soon and so the profitability of mining will go up several times. There was no blow off top so why do you expect a 90 percent drop in prices?
The fed will stop rising rates and crypto bull market will be resumed and all amateurs who sold their mining equipment will bite their own asses hohohoho
Are you talking about ASICs or video cards? With video cards, the situation is now very uncertain and after the end of Ethereum mining, such coins as Ravencoin or Ethereum Classic will not be able to give a good profit to all miners, so 30-50% of the remaining GPU miners will probably stop mining.
