Why is every one saying or assuming that 67 was not profitable??
The solver's answer says so
I see, one more question how many GPUs did you use to find it?
Several thousand
Calculate several thousand GPUs by 67 days paid rental,
the only other option he hinted is that it was found by a pool, then I will believe it was profitable.
Well from his previous posts you can clearly find out that he is running some kind of seed recovery business - so most likely he owns all his cards, or have some other (cheap or free) sources
