Thank you for suggestion.

There are something suspicious for me or just I didn't understood the difference between Solo and Pool mining.
More than 12Hours I'm mining with 10 computers ~3 KH/sec to my Wallet and still there are no ROI
When mining to Wallet, I'll get 120 ROI only when find block and nothing else during the mining ?
When mining to Pool, I'll get 120ROI when find block and some payment for the mining ?

I'm confused . Can somebody explain please
