Do you think the bitcoin mining rigs materialize themselves out of thin air? Those things get constantly replaced because they get inefficient due to the rising hashrate and advancements in chip efficiency.
that's simply because a PS4 is orders of magnitude more energy efficient than BC and was designed to be like that
BC on the other hand are very expensive in terms of energy consumed, by design
BTC don't make any sense energy wise and in the end don't make any sense to invest in something designed to burn energy in the long run, especially now that we are trying to fix the mistakes of the past
