I bought $100 worth back when they were at $.02, mainly to purchase some Kush on the Silk Road. But I chickened out.

So I'm in Bejing right now trying to find someone on the local Craigslist who will exchange them for gold.
Then I plan on buying a boat to smuggle the gold back into the US, along with a nice Szechuan wife to do my laundry for me.
