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?
