4 day in a row no payout .
friends that invest on ETH did not get their payout in the last 4 day.
maybe you need to wait for a while because i see there is delay payout from genesis mining itself and make sure that your friend can reach minimal payout for daily. because if we can not reach minimal payout, then it will delay until you can reach it. the other option, asked your friend to send ticket to genesis mining about the problem.
