Paying legal fees in BTCs? Better call Ryan.

Located in the desert town of Scottsdale, Ariz., Ryan Hurley is an attorney who does work for medical marijuana businesses, renewable energy and real estate. He managed to convince his law firm's top partner to accept the virtual money. But the boss is still worried about wild fluctuations in Bitcoin value, so they cash their stash in U.S. dollars every day.

Hurley already represents a few Bitcoin millionaires who hoarded them early and now want to launch their own businesses.
