There is no assurance that the prediction is true unless it will be happen exactly. No one in the digital world can predict in precise since each and everyone of us here try our luck and hoping that the price of bitcoin will increase tremendously. Soon in the future the price will extremely increase, just like on the year 2017 last quarter.
If it happens exactly then that is not a prediction anymore but that is already a reality but prediction is something that you are not sure if it will happen or not . If your prediction was about the pump of the price then go ahead predict all you want if that what makes you happy but for some people like me I don't say stuffs that there is no assurance because I don't want my feelings to get hurt if all thing turn backwards
