Supposedly on test network RX580 can mine 3 BTG per hour
On the test network there are very few miners that mine, because there is no profit.
When the real mining start, believe me, it will be very very different story.
My guess is that at the beginning will be maybe 3-4 times more profitable than the current best profitable coin on what to mine.
And when most of the miners figure how to mine it it will equal in profit with the other coins. For that to happen i give it maximum of 2 days.
Also this is a Chinese fork(Lighting Asic founder is the creator), maybe they well be already mining it with huge farms before the small miners join.
