Crypto went away from GPUs and onto ASICs back in like 2014, and then coins that once again leveraged GPUs came back. Ugh.
I am not opposed to cryptocurrency. At all. But I really think it's distasteful and severely wasteful for this to be a GPU-using business. The wasted electricity and economic waste are astonishing. Outside of a handful of coins which further protein folding simulation and other actually useful things to science and humanity, drawing mass power and heat output from GPU mining is a joke when it's just arbitrary numbers.
If an ASIC can be made to take over Ether/etc, it would be extremely helpful in so, so many ways.
