Following the files used reveals the pool and wallet used. The pool lets you look up the stats for this wallet. For this wallet, it says:
> Total Paid: 163000 TRTL - 42.16$
But I guess the culprit is rotating wallets. Judging by the hash rate, the pool estimates a weekly income of 700$. It could be a multiple of this if the culprit uses multiple wallets at once.
Anything with its own blockchain and also not popular is basically worthless
The mining rewards over a few months would still be just a fraction of a few million dollar marketcap network
But there are quite a few valuable ones you could get a decent take on, Tellor comes to mind.
GH hosted CI runs use Azure DS2 v2 instances. I'm not sure how GH is billed by Microsoft for compute, but the 3 year reserved pricing is $0.0405/hour.
So all up, that's around $2-4 of TRTL for $23.81 of compute.
Plus there's the real and opportunity cost of needing to assign engineers to try and prevent this from happening.
