Ok. Here's what I learned so far since I found bitcoin in it's beggining: it was designed decentralized as a currency (a purpose) but being decentralized it gave the power to the mass and the mass chose to use it as a commodity. Also learned a lot about myself and how I cope with all those emotions. Learned some trading, some economy. Learned that I can make profit by going down too, not just by hoarding.
I am trying to find out now, if bitcoin will go above it's all-time high this year. We all believe that due to the limited supply of 21 million coins, price for one will be high. But can this happen soon?
If, at some point in the future, the USD value of the goods people want to exchange using Bitcoin exceeds the number of coins held by people willing to circulate them by a factor of about 30, then at that time the price will probably reach 30$ again.
The only way for it to happen sooner is by speculation that that time will soon arrive, and any such speculation has a chance of being a bubble (of the kind we saw in June).
So I guess my answer would be that it depends on how quickly the underlying economy grows.
