Here there is a great problem with the pools. I have mined xmr and it pays to me a day what the calculators mark. I mining bipcoin I have left it several times because I do not see that the payments are consistent with the calculators, almost always it is the half. For example today, that it started paying well and then that the difficulty raised, it stops doing. With my speed, it has to pay me 1.25 Bip per hour at this moment but there is a payment that was late almost 8 hours and was 5.2 Bip
