The 1200 bubble was for the most part produced by WillytheBot (MtGox) and his followers. Cyprus crisis had about the same impact on Bitcoin price as Greece has right now. Problem is mainly, when the banks are closed, people are not able to buy Bitcoins.
Cyprus was loaded with deposits from wealthy Russian investors. When these billionaires wanted to move some of their money, Bitcoin was a natural fit. In the case of Greece, that is not happening. Even if the banks were open, Greeks would withdraw Euros and keep it with them.
Yes. Bitcoin is also much bigger now than 2 years ago. It is affected by Greece to lesser degree.
