I'm on pool many time and at once with low power find block on pplns, but don't know that Kano put a pig to all of us.
Very good, that blocks accepted without comissions by pool.
But how we can spend this bitcoins? I try to move 1btc, but transaction weight about 100kb, because so many inputs. It's the biggest comission.
I think it not more good as SPV mining with empty blocks. Blocks with synthetical rubbish - analog of empty blocks for network.
For miners pool Kano is pool with hide comission about 5-10% for use mining bitcoins by time.
Of course, if you power more big - this comission less, but for big money you need less inputs too.
Therefore people go out from pool, because china frends not so honest, but not do this harm to their miners and network at all.
Pool is vitally important minimal limit settings for output.
