Well, I just had my first default on Kiva... In hindsight, I did think the loan value was excessive for the country, but I figured it was worth a shot.

Updated stats:
Total loans: 257
Total lent: $7,325.00
Total lost: $2.88
Amount of currency loss: $0.18
Amount of default loss: $2.70

I'm still not disappointed. I've lost 0.03%. Considering inflation in the US is running ~2.2%, the US government's fiscal policies are more dangerous to my money than Kiva loans.
