trying that too. Have been paid already, low payout threshold too so great for cpu mining
Here i'm mining too, pumped a bit kh in the network ^_^ GL
all I've got is cpus so top hash rate I've seen and only briefly was 700 H/s !
You know, you can rent hashpower with ltc / eth (BTC not recommanded because of high transfer fee).
If you wish i can send you a private message with link to website where you can rent hashpower.
