Those who trust the project don't look at the price

What is the logic behind only buying a coin when it is at rock bottom? There is only one plausible explanation: maximizing profits when selling. If people stopped speculating and bought coins frequently, demand would be sustainable in the long term and the price would only tend to increase. A peculiar example is the OM coin, which has gained a legion of fans (I am NOT one of them), who are buying the coin regardless of the price. As a result, the coin is growing at an exponential rate.
