If someone buys a lot, then that someone is obviously bullish to acquire those coins.
If someone sells a lot, then that someone is also obviously bullish, trying to manipulate others to sell, so he could buy more.
There isn't a possibility in the universe that someone just doesn't believe in the long-term success of bitcoin. It can't be so! It can't!
So much similarities with religious folks.

The majority does not believe. That is the point. The minority knows that bitcoin have the properties to advance organically, and since there is no stopper, moon is where we go.
Edit: The minority have for a hundred years argued for sound money. The majority do not want to keep their freedom, because of credit card points! Ref http://www.forbes.com/sites/learnvest/2013/07/01/i-fund-everything-in-my-life-with-credit-card-points/
So someone invented a better form of sound money, that people actually want to use, proof: the usage growth. There is no religion here.
