But, place your bets where you wish - with such confidence surely you are shorting the market? Or are you just talking? I encourage you to profit from your foresight. Bitcoinica will give you 5:1 margin for a short position... why not come back in a month and tell us how much money you've made?! I'll personally apologize to you for my skepticism of your reasoning.
I keep seeing comments similar to this one. Not everyone here is for profit, personally I'm just very interested in what is going on for various reasons related to my day job. I have been negative of the implementation of Bitcoin from the start, but never thought of placing any bets, or trying to short, even though I was sure that the price would continue to drop.
The reason? I simply don't trust the exchanges. Not a single one of them. Not even to short. This I believe is a big part of the problem with BTC, the technology can be as resilient as anything in the world, but the implementation fails at the choke points.
