I think I agree with this. Tons of people try to make a guess but that doesn't mean that they act on it. If I guess that it will go up, doesn't mean I will buy, or if I think it will go down, doesn't mean I am going to sell.
There are two reasons for this, first of all I may have no money and do not want to make that move because of that, secondly I may not believe in my own prediction as well, maybe I say that it will go down but I am not sure about it either so why would I make a move on it, acting upon it means I would lose money if I am wrong, whereas writing about it means nothing to me at all. This is why it is quite important to actually do something about it, and saying something about it means absolutely nothing at all.
Which is why I have always thought that the accuracy of our predictions or our win rate should not be the main way to measure our success as traders or as investors, at the end of the day what matters is how much money you have in your account after a series of trades and whether or not you can beat the performance of those which just hold their coins, and if we are honest about it the majority of the people out there are unable to perform at the required level, which is why they keep speculating about the price but rarely open positions related to their predictions.
