I don't understand #6. It's A LOT easier to cash out then it to get USD into an exchange.
Cashing out is trivial, even. MtGox to Dwolla to my bank. Less than a day. The other way around, my bank to Dwolla to MtGox, took over a week.
World banking system favors citizens of USA.
It is custom barriers and currency laws in other countries which make caching out harder.
You can say I'm nit picking, but that ruined the joke for me. Funny jokes are baed on truth, not lies.
In order to determine is it truth or lies we need to know percentage of non-American based bitcoiners.
