I agree. If someone makes a prediction which ends up being wrong, they just forget about it and it goes away. But as soon as they make one which by sheer luck is right, they jump up and down saying "I told you so! I know everything about Bitcoin!"

Besides... If you know for a fact what the price will do tomorrow, why the hell would you share your secret inside information with everyone else? You'd use it to your advantage to make a profit.
