I'm curious if this got resolved. I just tried middlecoin for the first time. Mined roughly 24 hours at 1500-1800 kHash/sec. I see my wallet address in the list on the site, but no payout seems to have ever occurred. Nothing in my coinbase, and the payout column is empty on my address. Not sure what's up, and no real way to contact. Not sure if I should keep at it, or if I'm wasting my time there. I wanted to compare 24 hour results there vs multipool.
if u check his address on list u'll see he stil mining, and he got already .61 BTC
middlecoin mining mostly DOGE, and it stuck sometimes on market.. so u see many "unexchanged balance"
if u mined ~24h with ur 1.5-1.8 MHs => u should see ~0.02+ BTC overall (immature + unexchanged + balance)
u will get ur money 1-2 day later when mined coins sold AND ur balance > 0.01
