I’m also at that scale and can tell you that microdust will build up on fans and become an issue. Cards require maintenance every 4-6 months to perform optimally and to ensure longevity.
I’m not suggesting you host rigs for free, just build it into the monthly price rather than a hidden electrical fee. I think a good hosting service is needed, but you have to expect that experienced miners here are going to give you a lot of scrutiny so that new users don’t get taken by a half-baked host arrangement. You would expect that of any random user on here offering something without any website documentation.
Also, I’m interested in seeing your hosting contract and if the location will be insured in case of fire, etc.
It is clear your experience in this sector is quite limited or that you are a troll
That’s really unnecessary.
