I disagree about the stability of bitcoin. Though I will not ever use it as physical currency, I do see it as an easy money truck.
The reason it's not unstable is because what is the true value of a bitcoin? It's not like a stock, it's limited supply, and has monetary value. I think bitcoin will steadily climb until some government cracks down on it. It will become of, who pulls the trigger closest to the top before some company cracks down on it.
I wanted to buy so badly when it was at 110ish but bitinstant temporarily removed the cash deposit option. I was literally sitting outside a walmart hitting f5 on my laptop rigged up to a mobile hotspot trying to get it back up.
I decided to head home and checked about half way home when I noticed bitinstant was accepting cash deposits again. Bitcoin prices were about 130 at the time and I decided to insta ship the next exit and sit in a cvs parking lot and get the bitinstant transfer ready, when all off a sudden dead stop traffic. I've sat in traffic for about the last 2 hours. By the time I got to the exit bitcoins were already back up at 180ish so I scrapped the plan. I'm so pissed about this right now, it was obv a moment to buy.
