Ok then, so please explain me, how pool will be buying BC? for what? some BC will be contributed by miners as fees so pool will withdraw them to miners again. But what about rest? Pool need to have BTC to by BC on open market. How will they earn BTC to buy BC?
... by mining the most profitable alt coins, selling them for BTC then buying BC with BTC.
In short - transferring the VALUE from alt coins to BlackCoin. Direct transfer of value from ALL profitable alt coins IN to Blackcoin. One way value transfer
Why is it one way? Because ALL BlackCoins already in circulation, only 1% per YEAR inflation. Value is only increased - not decreased or diluted.
But on the pool alt coins will be mined by private miners. In case which you are descirbing they need to set up their own rigs to mine alts, and exchange for BTC, then for BC, and these BC distribute to miners. so littlebit pointless, or if fees will cover power bills from their mining rigs ang multipool servers..
