US: Hello, China. We like to make another loan.
China: No problem! How many bitcoins would you like to borrow?
US: What's the interest rate?
China: Zero! Just pay back the exact amount of bitcoins we loan you and you're golden.
US: Can we repay you in dollars?... Hello. Hello! Helloooooooo!
US: Hello, FBI. We would like to borrow only $1B of the money you have from DPR's old account, and we promise to pay it back with dollars after the trial.
FBI: No problem. We'll simply call Mt Gox, where we stored it for safekeeping, and have it transferred probably within 24 hours.
US: You guys are the bestest! Wait, what. Did you say Mt Gox?
