It's not all that great. Many rushed to mine BTG as soon as it launched. There had been many ranched mining rigs waiting for something like this and the hashrate that rushed into it was too much. Luck for 1 KSol/s is currently around 300 days. That's how much it'd take for a miner with that hashrate to mine a block. Do the math and it doesn't seem very profitable compared to other alternatives. Perhaps many mining it are counting on a price increase.
Weird whattomine.com showing BTG on top now. But reading some threads here looks like there are lots of crappy pools.
Anyone with solid figures on BTG mining able to confirm what the daily yield is like and on what hardware.
My 2 rigs with 12 x GTX1060 are mining in suprnova (it fluctuates but I think average hashrate is about 3100sol/s), daily yield is about 0.055-0.07 BTG, I mined exactly 14 days, so earned 0.88 BTG.
