Since the halving, BTC mining profits have been decreasing, with the reward for each block now only 3.125 BTC. For machines with a hash rate below 100 Th/s, it is increasingly difficult to be profitable (considering a normal electricity price of 7/8 cents). Many small and medium-sized miners have expressed a declining interest in Bitcoin mining. Apart from large mining farms and publicly traded companies, what cryptocurrencies are small and medium-sized miners currently mining?
Mining is an investment, and investors consider the return on investment (ROI). Let’s examine the market from an ROI perspective to identify which machines have the quickest payback period.
