I have been mining for almost 4 days and my balance is currently 0.01829838BTC. No payment made yet. Any idea what happened? My wallet address is 1NpPSHr34XCByw2jHPaBsEMGccQcBjzMQ3.
You were paid just few hours after you posted this. Payouts are scheduled daily so you need to wait for the next scheduled payout after you reached payout balance. I see your payouts are running without issues.
