I'd say just rent out 5PH from westhash and mine against your own node.
Has anyone ever made a profit by renting from westhash and mining at solo.ckpool or only the miners at westhash make the money?
Simple statistics ... only the rental company charging a % fee is expected to make money out of it.
Block finding is random, so of course some win and some lose, but it will average out to only the rental company making a profit.
Oddly enough, that is blatantly obvious, but it doesn't seem to stop people renting ... ... ...
We had a solo group renting hash with phil, we got two blocks after a couple of attempts, was like attempt 3 or four. i think we got a tiny bit more than when we started.
