You are grossly overestimating the depreciation of mining hardware. It’s pretty common to have well maintained mining rigs and farms that last several years. Also, it’s a common strategy to sell mining hardware at or near ROI time to essentially double your initial investment. Coincidentally my GPUs have not only paid for themselves and then some, but I could sell them used now for more than I bought them for. I’m lucky in that respect.
