I never heard of this compassmining I tried to search and pointed me to compassmining.io is this the site you talking to?
If yes then I never heard of this website before some old posts mention this site but almost all posts are made by newbies. So I can't give any insight if they are legit or not.
And I checked their website and some guides but it looks like they are not offering a hosting service but selling mining units and hosting it to their hosting partners. We do not know if they have these units physically and it seems a cloud mining.
It's too risky to deal with them without the units physically and look at this below just copy and paste it to your browser I just want to link them here. According to the link, you can't send your own miner to their facility unless you buy from them which we don't know if they have these units on hand.
