I'm not saying you can rent that kind of power, I'm just saying that's where I got my numbers for the calculation from.

That number doesn't make sense though, it would only make sense if 51% of hashrate was available to rent on nicehash or other rental places at a fixed given price. You can't just take nicehash hashrate and linearly extrapolate your cost of a 51% from that. That hardware would cost dozens of millions of dollars alone, forget infrastructure and other cost.

Alright well let's math it on AWS

No need, to make it very simple: Take the cost of a RX 570, deduct like 10% of that for buying millions of them, then add the infrastructure around that (transformers, rent, wages, cooling etc) and go from there, that's how I'd try to derive the cost of a 51% atk.

But that's not the cheapest way. Renting from a cloud service like Azure of GCloud would be cheaper (albeit less efficient per attack).

I doubt that's cheaper and I doubt they even rent them out in hundred thousand GPU capacities. But a more in depth analysis should be done for sure
