Can I predict things or what!

The faster it goes up, the faster it comes down...it was $5-6 a coin for months before people went on a buying spree. And you also have to remember that you're not trading with a company or robot (for the most part) like in the actual stock exchanges. You're trading with a person...and when those people bought coins at $5-10 each (or more) and they see it go up to $15, what do you think is going to happen?
