This is probably asked everyday and I apologize, but does this pool take 20% of what you earn on top of the 2% fee? I can't find a solid answer anywhere.
2% for crackfoo + an additional 5% to pay for transaction fees. So, 7% total.
5% is to cover the discrepancy of the price you're paid, and the price the coins actually get sold at because 98% of the time, when the pool sells the coins, they A) fill the order at the top of the market at the price your estimated at, then into the next which is lower, and then the next lower etc.... often times I'm loosing this % as the price by then would dip more than 5%.
