DEAR FREINDS,Some btc sites are like this, they are cheating ,there is no mentioning in their FAQ & in their HOW IT WORK rule.But they directly try to  apply the rule that after we mined since three ,four months,If we try to claim the BTC as they mentioned in their FAQ that:-"the mined BTC you claim after 0.005BTC". Then they will aply the rule which is not mentioned in their FAQ,e,g,YOU MUST PAY SOME BTC TO WITHDRAWAL YOUR MINED

BTC THAT IS LIKE 0.0001BTC.
