I spent money on three gtx1660 ti for 430$ each from china and I've only make 150$ back today, I'm worried when will I break even because so many people told me I did the wrong thing, they told me bear market is that I will never make my money back, is this true?
Depends on how much you pay for electricity. If you have free electricity, you will definitely break even eventually. It may take longer for you to break even, but it will happen.
