Hello,
after four days of mining with around 800 kh I have only some 7000 coins, what's wrong?
Regards
Hello,
Network difficulty is high, network hashrate is high, pool hashrate is low.

Nothing is wrong, this is how mining works on a pool with low hashrate.
Time Since Last Block 41 hours 7 minutes 26 seconds
Difficulty 394.61
Net. hashrate 28,099.18 MH/s
Pool hashrate 32.04 MH/s
