Will bitcoin collapse??

A quick look at the trending on steemit you can see a lot of articles about bitcoins and other coins. And I wonder why people really buy them, because It seems to me that everyone is hoping that one day bitcoin will rise so high that everyone who has it will make a fortune. Some people will, and many has already. But everything that goes up, will sooner or later go down as well. And since everyone wants to become rich on this coin believe that the fall is really close, but what do I know - maybe this is even just the beginning. What do you believe?
