Nvidia calls cryptocurrencies useless for humanity.

Nvidia's chief technology officer Michael Kagan said that cryptocurrencies are "not good for society".

"All this crypto stuff needed parallel processing, and [Nvidia] was the best for that purpose. People were buying and programming our devices for use in mining. They bought a lot of those things, and then cryptocurrency finally collapsed because it's not useful to society. But AI is useful," Kagan stated.
