I mined Ethereum in azure during the height of the crypto boom, and looking at my statistics of vms i was able to get i am pretty sure some other people did to.
On 5k$ spend on azure i got round about 7k$ in Etherum when sold the next day, this includes german Sales tax and some loses i made starting out when not accounting for the german sales tax early on.
I think the whole timeline where this worked was about one and a half weeks(Germany, if you played around with exchange rates and sales tax potentially a bit longer), but it worked pretty well.
fully functional? 7.12.2021 alone was enough to kill that statement for the next few years.
