I run a small forum with 150 or so dedicated members. The site renewal came up and instead of asking for cash donations I posted my BTC wallet and only accepted BTC.

I received 0.00BTC.

Guys posted complaining that they wanted to give but couldnt figure out how to get BTC. I had posted links to various methods but it was too much of a PITA for anyone to do.

I think that's the barrier...it's too hard to convert your government money into BTC. Too hard and takes too long and costs too much.
