I had to bring some some money (hundi) to the US recently and the whole incident gave me a new awareness. I found people who are ready to give me thousands of dollars in cash. Someone was willing to leave $50K in cash with me first as long as I promise that I deposit money in his (or his accomplice's account) in Nepal. I don't know this person at all. I am convinced that it is not hard-earned money. I just wonder what do people do to accumulate this kind of cash.
