Hi! I recently started mining and I was wondering if it's better to buy one or two GTX 1070's or three Innosilicon A4 Dominators (minimum order quantity is three..) A 1070 costs ~620 USD and the A4 Dominators cost 3400 USD with a PSU and 3150 USD without. It would be cheaper to buy 1070's instead. However, in the long run I'm pretty sure the A4 Dominators would be more profitable. Right now I'm leaning towards the Dominators. Should I go for GPU's or ASIC? I'd really like to know what you think about this. Good day to you.
