as a daytrader for 12 years i know exactly what this guy is saying. I actually predicted my own demise when I bought at 30 bux but I took the gamble since this is not like stock trading...(i only invested around 10k which is fuck all in trading terms) this market acts as a share market with all the classic signs and follows, and also is different.. all i can say is if your not a professional trader i would suggest you sit on the sidelines for now or you WILL be fucked over.. I am waiting for gox to open and cash in on the panic selling. what i have lost so far is nothing compared to what I expect to make cashing in on inexperienced computer geeks or first time traders in this market. I will have your scalps.
The reason I am in the hole atm is because I didn't think a decentralised, deflationary currency would exhibit the same traits as a commodity, but it does. Human behavior is the single point of failure in this situation.
as stated in the OP my biggest worry is the exchanges, they are the next single biggest point of failure you people need recognise, more exchanges are needed that are backed by someone big.. or this will remain in the realm of a fantasy nerd currency..
So now that you recognize that Bitcoins act like a commodity (only you have even more noobish and predictable folks in this market than you would in a typical commodity market), you're going to sell everything you have, buy back when the price hits rock bottom, and then play the market as if it were any other commodity?
I'm not a daytrader, but if I was, I'm sure I would be doing the same thing. This is by far one of the best places for daytraders to make money, simply because so many people here are so new to commodity trading and rely on emotions more than anything else.
