Did you purchased your bitcointalk account? By the looks of it you are a full member in bitcointalk and you are saying that you have no idea what makes any crypto currency go up or down, that doesn't really compute well with a full member account. As we all know people thinking that bitcoin will go up and buying bitcoin makes it go up, and people thinking it will go down and selling bitcoin makes it go down, that is literally the only reason.

There is really nothing more than supply/demand mechanism at work here, that is valid for almost everything in life as well, same as gold for example, same as silver, those do not have a real value neither unless you actually use them for manufacturing something, but most people do not "use" gold, they just buy it as investment and that's it. Same logic applies to crypto as well and there is really nothing to be shocked about it.
