That's the away it is with other things:  if I deduct a home office or the costs of employees, contractors, business trios etc....and they choose to audit they presume guilt until you can prove otherwise.   The more complex the thing, the more proof required.

I would rather steer clear.

I wish this would work, I really do.  I haven't done IRAs of any kind for probably 5 years or so...I used to do them all the time.  If I could confidently depend that a system like this would work I'd do it today, have a huge press release that our firm accepts Bitcoins in IRAs.....I bet we'd open 10,000 new accounts in a week
