Any available rented gpu power?

[woookash]

Hi,

I'm looking into running some stuff, and I'm wondering: is there any calculation power that we can rent?

From my research, I understood that:

- Amazon instances are ridiculous - way not enough powerful
- Bitcoin mining rigs: from what I understand, it's just impossible

Can someone confirm both those points?

And has anyone any idea where I might rent some calculation power usable with hashcat?

thanks ;-)
