There is always a bubble, for some people going 1 to 10 was a bubble and for some 10 to 30 and then 500 to 1100 
When did it go from 500-1100?
I think you mean 100-1100.
You must be the new guy.
LOL, so it went from 100 to 1100 without crossing the 500
? i dont know i am new or old but i started when it was 70.No, it didn't.
After the silk road bust announcement, the price dropped to like $60 or something for a little bit before recovering back to like $100.
It didn't rally to $1,100 until like a month later.
The rally to 1100 is mainly due to the demand from China. Now that China is actively putting up policy to discourage bitcoin usage, it is hard to see which market can replace China market.
