My point is that I don't get what is the "killer similarity" between BTC and Rhodium. Yes, Bitcoin is a "digital commodity". But its "digital" form is not only an adjective, is a very important characteristic that makes Bitcoin different from any physical commodity. It can be easily transfered, transported, hided, divided, etc. Stores of value are needed, they provide an utility, and Bitcoin is a huge improvement in utility over physical stores of value because of its convenience and "digital" characteristics. Plus, you have the blockchain, which is a fascinating, multi-use beast by itself. Then, you have colored coins applications. The possibilities Bitcoins open go well beyond its similarity with physical commodities. I really think that saying that in the long term Bitcoin will probably behave like Rhodium is baseless.
My point is it attracts the same kind of crowds, fringe types and salesmen personalities. I view Bruce Wagner, Max Kaiser or Bitcoin Jesus not different than those types who sell "Rare Rhodium Proofs" on a TV-shopping channel. It's the same kind of Gold-Digger Mentality, hordes of people thinking they are on to the next big thing.
I am probably more overall bearish than you when it comes to fundamental use of Bitcoin, but I don't think it's certain this Bubble will collapse the way it should. For all I care we could shoot back up to 200+ within a month or so.
Only within a certain short timespan of about a few days to a weeks I think Bitcoin can be predicted with enough accuracy to trade it successfully. And even then it can only be predicted in certain cases.
