The headline says it all. A short google research brought only "impossible" and similarly useless answers. There is a conspicuous demand, so it is done somehow. The question is how. Let's collect a few ideas and strategies! What I am planning specifically has to be completely white hat, legit and unsuspicious in case the fiscal office finds out and wants to take a closer look. So no shady bitcoin dealers or betting providers, no fake accounts, also no risk if not absolutely necessary. But I am basically open for every interesting solution, maybe it's of value another time or for another user.
