thank you for a quick reply, Graet. my plan was prop because in that case i, as the pool owner, will never go bankrupt since payout amount is always the same and does not depend on round luck which is just the same lottery as sdice or anything.
i planned to make a pool with limited registration and monitor it so that users will mine fairly(no botnets, no constant hopping in when hashrate is low). i have to create a valid TOS for this. do you think it worths a try?
i didn't dig into other reward systems currently used, but since they are all based on PPS, so i can't really play this casino without being afraid of going low, is that correct? so i thought maybe i'll set up a proportional pool and keep an eye on it while i can so that it will be fair for both miners and myself.
