i started to mine spreadcoin on 3 jul and first day i found 12 blocks, on 4 jul i found 12 too, on those days difficulty was 120+, yesterday i found 8 block and difficulty was somewhere at 130 and today on 140 average difficulty i founded only 5 block in 22 hours. soo something is wrong. on 16.6% difficulty increase i lost 58.4% in chance of finding blocks...

i have an gtx 1070 which have 7.2MH/s and found only one block in 36 hours, 18 hours ago and an gtx 1980Ti with 6.5MH/s which didn't find any block on 36 hours of mining...
