Where in hell is the money for withdrawals coming from? If SCC isn't really mining then how can they afford to payout anything? The random selection of who gets their withdrawal is all an illusion. Its to make people believe that they are still "paying" its users. As long as they have that there will still be some suckers to fall for it and deposit some Bitcoin hoping to make a profit but news flash:

Getting your money out of there is basically a gamble or a lottery at this point. If your ticket is the lucky winner this week then congratulations.
