these fees are simple math. you can stake 1.5m to masternode, or to pool. 1.5m is ~75k rac and this is about 10k bbp/day vs 4k bpp/day from masternode
so fees are covering losses to not stake as masternode
but 65% is still better than 0% for most of beginners...
You inconsciously forgot the cost of generating 75k RAC, which is about 600-800 a month.
Of course, this is not the case for the people that are hijacking from his boss' hardware and power grid.
The operator of the pool should be able to, in my view, get a return that is at least that of what they would get by running Sanctuaries with the stake. I would predict that to run the pool, it will need to be staking close to 9M BBP in the very near future (that would only cover 450K RAC which is roughly 6% of our total team RAC). With 9M BBP, the operator could run essentially 6 Sanctuaries as far less cost and headache. Right now a 450K RAC would pay about 70K BBP/day, 35% fee would make the operator just under 25K BBP/day. 6 sanctuaries would make roughly 23,500 a day. So if anything 35% is to me unfair to the operator and insufficient.
