Two thoughts, whatever mine are worth..
That OP considers 10c a deserving electricity price to mine at gives me the feeling they've a lot more research to do, I mean that constructively not entirely dismissively!
That I am new myself (and couldnt even work out how to vote in the poll) but I think OP is very much correct that Bitmain is dirty tactics through and through. However the article is very strange, Jihan is no longer CEO for example, at least I thought that was the case? Also 5 nanometer just sounds like nonsense for now?
10 cent power used to be the cutoff for mining.
It is now more like 6 cent power.
Bigger industrial units at 3000+ watts drive mining into the go big or go home camp.
Or mod an s-9 as a space heater in the winter point it at solo.ckpool and hope.
here is hoping:
