that new cat diff is stupid. like big waves and when diff is high no one mines it.
You can blame the switchpools and multipools. Right now, difficulty is at 2.. Set to go back up to 200 within the next hour. What a joke. CAT deserves to die. Switchpools need to die too.
You cant´f forbid these pools. They are part of the market, but you can do something to avoid these problems - see my post above
