i got the same problem



 been mining  for 137 days on clever-mining pool ......i don't see the point of mining any-more with my 2.2MH/s (gpu),with litecoin  getting more difficulty  and   the per MH/s rate dropping every day.

so what should i do  invest more (gridseed) ? or just stop ,as the power bill is more than profit these days Sad

thanks
