In last 22h (since my last manual payout) I have only 52 UVC (equivalent of 0.001BTC) but in reality I shuld have around 600-700. Yesterday when I last check they were 300 UVC (before 8 hours from now). Where are my coins, cause is impossible to mine with 3.8MH/s for 22hours till now, and have only 52UVC.
