I suspect we're in for another gradual climb with occasional dips and peaks until there's yet another media blitz around it. Whether it will reach a tipping point and become actual, you know, currency, for a large percentage of people is up in the air. But, it's already got some value for a lot of people.
For one thing, Coinbase has consistently run out of Bitcoins the last few days.
For another, I think a lot of folks will make their first purchase on Bitstamp, since it's really the biggest exchange now, and one of the most professionally run.
I'm gonna assume you're outside of the US; the difficulty and expense of sending an international wire from a US bank is rarely grasped by people outside of the US. My bank charges $40 for a wire transfer in US dollars, and more for one in the destination currency. My first BTC purchase was only ~$300...the wire transfer would have been more than 10% of that.
I agree that Coinbase running out of coins would have had an impact. But, I noticed that they were replenishing them relatively quickly...I tried to make a buy one evening, was told the daily coin limit had been reached, and an hour later was able to buy, and bought a little more the next morning.
I suspect they were sitting at their computers all night during the run up to $1000, trying to manage fraud while also trying to buy and sell as many BTC as possible.
Anyway, I'd be surprised if there's another big spike...but, a gradual climb back up to $1k and beyond does seem entirely realistic to me.
They're also a direct exchange, and if they started to run low on coins (thus driving the price higher), someone would happily provide more coins via arbitrage from elsewhere.
They reportedly prevent about 3% of orders from going through for that reason (and I seem to recall there was someone complaining about it here in a previous HN thread, as they'd run into the fraud filters and couldn't place an order as rapidly as they wanted).
They also limit less verified accounts to buying (I think) 1BTC per day, so someone doing it to manipulate the market (rather than simply by BTC fraudulently) would need to create hundreds or thousands of fraudulent accounts, back them up with a US bank account (or some other supported funding source), and then get past the fraud filters.
To raise the daily buying limit you have to verify a credit card, and perform other verification steps. I think it's more careful than my bank about security; at least on the surface.
Are you bonkers? Price rose nearly 10 times in about a week. That's practically textbook definition of a bubble. Wait until it crashes and comes down to 200$.
