Or roughly 1.3M GPU hours. Less as GPUs get upgraded. Not sure how many AWS F1 (FPGA) hours it would take.

So somewhere between $300,000 (running consumer GPUs cheaply) and $30 million (paying AWS on-demand prices for Tesla V100).
Even the upper bound for that seems well worth it for well-funded attackers if the target is juicy enough.

Consumer GPUs could be run from a botnet, actually... Yikes.
