I can see the pros and cons of bitcoin. Cons are it could be the next Tulipomania. Pros are its supply is fixed, decentralized, governments destroy their currencies, and if this continues to survive it could be a currency that is used in everyday transactions worldwide. I don't really lean either way, but I do think that even if it is a giant ponzi scheme its somewhat interesting that a lot of people are about to get invited to the ponzi party. Supply is essentially fixed, and demand might go up a bunch as it becomes much less of a hassle to throw a few sheckles at BTC. I don't directly own any but am participating through a position in FRMO.
