Then run an anonymous hedge fund.
Gosh, that's a novel suggestion.
I guess there is that teensy weensy inconvenient little detail that if you'd like it to be exchange-traded, then you'll have to turn over a high-resolution copy of your passport, driving license, and other documentation to somebody who declines to provide his real name, does not operate in the context of a real company, does not provide a real data protection or data retention policy, and cannot be held accountable for potentially illicit use of your identifying documents.
But as long as you're happy with all that, you should be good to go!
What's that, you don't want to hand over all that detail to an exchange? No problem then: just find some dude named 'Guido67', give him some cash, and hope for the best. I mean, it's all anonymous, right, so who cares whether Guido67 knows up from down?
