One of bitcoin's biggest problems is adoption. How do you get people to climb the steep learning curve? Thankfully, the U.S. government has pressured financial services firms to cut off access to legacy money to recreational drug enthusiasts and sex workers. Now, adoption of Bitcoin is tied to the satisfaction of the most powerful urges known to man. So, thanks for that, Feds! When the rest of the world finally ditches your inflation-prone fiat for bitcoin, we'll have you to thank for boosting bitcoin over the early adopter's hump.
