I do not agree.
If 10 people joined up together on the main pool you still wouldn't get such a large share of the prize. as the rest of the pool takes a slice too.
Here if we team up some hashrate the payout would be much much better.
If that were not the case why would 10 people throw 0.125 btc at a "shot" at the block.
Why not just point hashrate at it?
Dear friend, ten member with 500GH? what that means? I would cooperate when this team is able to collect at least 2,000TH. I can provide 200TH.
