What are the benefits to use those Pool instead of roi.optiminer.pl ?
Many small confirmed payouts vs few huge but unconfirmed payouts
The things are opposite but OK

, the small unconfirmed payouts are in Optiminer , and what prevent the Pool owner not to pay miners. Because in Optiminer , miner get the payout on each mined block.
The exact question should be, does suprnova is more profitable than optiminer?
