Speculation is both good and bad, there is no easy way to say this but that is the truth my friends.
Speculation sometimes help pump the price of certain coin when people hear some great news about that very coin.
In the other hand, speculation may also be used to create "Fake New" to destroy or dump certain coin by competitors or big whales.
You can look in to this from both angles. And this is true its good and bad.
But this is just opinion if you look little bigger yours/mine/his/hers and in the end it will be like we want to hear it or read it. You can take this or that speculation what you want cuz in the end speculation is form of a theory without any hard evidence.
