As compared to when bitcoin was at 2 USD there has not been any increase in trade, and no new businesses or services that are attracting more bitcoin trade than usual have opened up. Because of this, the real value of the bitcoin economy has not increased. The only thing causing the upsurge in price again, are greedy people who are speculating that prices will rise even further in the future. This is how you create a bubble, and that's what is currently happening.
No, your absolutely incorrect.
Whilst I agree we need to protect ourselves from over speculation which could induce a bubble, your above statement leads to me to believe you have no idea what your talking about (I wont hold your low post count against you)
Your first point of no increase in trade, just by looking at the charts linked below, your statement is a total fallacy.

Cant you see how much trading volume has grown in the past 5 months?
Your second point "and no new businesses or services that are attracting more bitcoin trade than usual have opened up" is personally insulting.
In the past 5 days since we launched Instant Bank Cash Deposits @ BitInstant, we've seen over 30k USD in cash deposits- ONLY in cash deposits.
Since we've launched, we've transferred over $1.2m USD. 40% being first time Bitcoin buyers
Are you really gonna sit here and claim "The only thing causing the upsurge in price again, are greedy people who are speculating that prices will rise even further in the future"
I can leave it at that, because I know the hundreds of Bitcoin business owners will be replying to this post to defend their accomplishments.
Thus, I conclude while I agree we should avoid a bubble- you should also avoid statements that you cannot back up for factual evidence and proof.
