I'm in. I think many are blocked by the volatility. They can't afford it. And the solutions to spend-and-replace have spreads or fees.

Personally, I'm willing to push through the above to bootstrap. I consider it charity paid to a better future.

BUT - I personally can put my finger on a single blocker I have. I haven't seen it discussed anywhere and I anxiously want a solution.

The only reason I don't wander around asking completely random merchants or general labor contractors if they accept bitcoin, in my neighborhood, is because of the safety aspect. I don't want my house to become a target. I don't want for it to be labeled as "the house where the bitcoin guy lives". I don't want to offer a job to somebody, then they mock me to their criminal-in-the-making friend.

tl;dr I think I need a citadel first
