Well , it is difficult to find genuine mining websites which pays instantly after reaching minimum payout.
I have got few payments recently and Link : https://goo.gl/YjSDr5 is one of the website.
First , i started with free, as it gives 1 MH/s free. Though it is slow , i keep on buying MH with the coins i got for free, after couple of weeks, (yes you heard it right - 2 weeks) reached min. payout and instantly cashed out.
Now , i got the proof of genuine payments, invested some amount to buy MH , and withdrawing profits daily.
