Bitcoin is my personal bank, Thanks to Bitcoin, I can keep my money without being connected to any center. I don't trust Banks and capitalist system.

As for your question, the short answer is because most people are selling and not buying or holding. No reason to sell the coins though, so I can't actually tell you why bitcoin is going down. 

I think it will but it will take a lot of time, maybe in about 10 years.
