I mined BTG in suprnova for 24hr since the start, 4 cards yield 0.06BTG. I feel the payout should be much higher now because the pool was congested at the start and nicehash had channeled huge hashrate there causing me to get very little share in payout. But difficulty is still increasing now.
Nevertheless, I am back to zcoin since the difficulty there seem to drop somehow and the pump in price half day ago made it viable again.

PS: I found a BTG profit calculator for you to know a rough estimate http://calc.btgpool.pro/. And yes, I know calculator is not accurate, so don't bombard me.
