Many people seem to have a few things wrong. firstly, it's not profitable to mine bitcoin with gpu's. The ethereum asics are out, so mining eth with gpu is not profitable anymore, at least if your thinking of buying an nvidia or amd gpu. You can mine the small cap altcoins with these and, after mining for awhile, if the go up 10x or more it may be profitable.
Just wanted to update people on the state of cryptocurrency mining and give my two cents worth. Good luck and have fun. As always this is just imao
