Minergain - I'm currently running about 100 S9s, with 10 more coming online Friday morning and 11 Avalons on order. I recently switched from Slushpool to Kano due the fee difference (and discovered a much nicer user community as a bonus). For me, its just business - I will make more at Kano than any place else I've found at an acceptable variance. Kano's example was 7 BTC difference, but does it really matter if its 7 BTC, $5000, or $1000 over a year? Its still more.
I started at slush too and switched here to get a bigger piece of the pie with my single S9. When I left slush in August it was around 250 Ph and Kano was around 40. Amazing how that has changed in scale. Yes, more money is always nice to have - and if we get really lucky, we all get to actually take part in a nice bonus. Plus I have not found a better community of crypto people anywhere (and super willing to help everyone learn). Welcome to Kano and Mine ON!
