A while ago, a user went around saying that if you write certain words in your signature the price of BTC would go up, otherwise it would go down. 

People believe in many superstitions. Many football players enter the field with their right foot, as they believe that this will make them successful in the game. Others say she has a pair of lucky panties, and when they wear them everything goes well. Some I believe you have to do a certain kind of thing before something, to be successful. Anyway, the list is huge.

If these people think that doing push-ups or other physical activity helps the price of Bitcoin rise, that's fine with me. I already know who to blame when the price drops. 



As for the speculative aspect. Well, speculation is speculation, no matter how you do it. What you may question is whether the speculation argument is logical. For some it will be, for others it won't. It's still speculation, even if it's unrealistic.
