Why exactly 275$? Will OP as the same question with another number anytime the price changes?
(If it goes to 250$..., If it goes to 1$..., if it goes to 100000$....)
What is so fraggin interesting about what the people do when the price hits 275?
Looks like you don't really understand how the market works

On the market, that I understand, I bought some BTC for less than 100$/BTC and sold a few for 800$ (could have been 1200$) and invested some for 500$. Now I make some BTC on a regular basis, without doing anything. I don't mind if the price is 275. I would maybe start buying below 200 or even less.
Looks like you can easily explain why 275$ is such an important number. Please enlight me.
