How liquid are bitcoins and other crypto-currencies ? (i.e. How easy is it exchange them for normal currencies or for goods and services?) For example, in the USA, a person with foreign coins (of the physical variety) can't go into a typical bank and exchange them for US currency. Is getting...

I recently heard about bitcoin, but don't know that much about it. I read the Wikipedia article, but it wasn't particularly enlightening. What are the prospects of an alternate currency, like bitcoin, being viable. My guess is probably not much since it lacks the coercive power of a...
