SPR is no a solo-mining(decentralized)coin any longer
Wrong.
So you are the owner of that pool and you confirm that SpreadCoin can not be pool mined? What for is then this pool? Is it only for trusted miners?
Correct, it is
extremely unlikely there will ever be any other pools, this was merely a test to that.
For example a noob comes in here and ask wheres the pool because he wants to mine this coin. We can't give them one cause there isn't one. lol So we Gotta tell them there is "no pool." you have to solo mine cut straight to the chase because there isn't a pool.
