It's not only this, I would recommend you to not buy any GPU right now if the GPU costs more than $200, alts rose because of eth and eth profitability will crash by half and maybe by 75%, you trolls need to understand that there are things eth devs are considering and the first thing is, in few weeks the network instead of right now is 16 seconds to find a block, in few weeks is going to be 30 seconds, that is half the profit you are thinking of, second there is the possibility eth will also be reduced from 5 eth per block to 2.5 eth per block, that will be another half and that will probably happen within weeks and there is the chance is going to pos which will make mining pretty worthless, so forget about mining if rx 570, rx 580 are more than $200. Rx 570 and rx 580 will be sold for $100 in few weeks. If you have the money now, I would advise to buy eth and hold, that will be an easy 400%, but make sure you sell once it hits 150 ~ 200% because it might crash hard hehe
