No matter what you do hosting a hidden service from home is retarded because chances of the FBI and other feds not being able to quickly trace them are pretty much zero percent. I would like to continue to cling to the fantasy that FBI is an entirely incompetent organization, but the step by step instructions for how to trace hidden services are contained in whitepapers on the public internet so its really a stretch to think that they can't at least pay someone to do it for them.
