I have a fundamental issue with bitcoins that I have not seen anyone address. Sooner or later a better bitcoin will be invented. One that can perform transactions faster, or is more anonymous or where mining for the coin helps some nice project (SETI@home, math proofs, protein folding, etc), or something completely different. When an alternative better currency catches on, at some point it will become obvious that bitcoins will be obsolete and the value should suddenly be 0 again.

It is the nature of technology that bitcoins will someday become MySpace.

I am open to be convinced otherwise by someone knowledgeable.

Not always the best technology is the one which success. If that better bitcoin is invented too late, bitcoin can have a large infrastructure and accepted by a large proportion of merchant to be switched. Just think about VHS and Beta or OS/2
