The only thing that matters in mining is the time of selling your coins.. If you mine and keep your coins until ETH goes back to 1000$ you hit the bingo... You should NEVER watch what is the best coin to mine at current prices... (you should only if you are selling coins right away into $) This is the thing most miners are not capable to think about it.. Thats why every 3rd guy is crying about how shitty is to be a miner nowadays
