How to Use | Try Actual Prediction

Once the user chooses a topic, multiple choices will be given automatically. The user can either pick one of them that suited his or her prediction by tapping, or add a new prediction. User gains 100 points simply by predicting.

Furthermore, sharing the prediction to SNS account will give the user an additional 100 points.
Predicting of each topic gains 100 points, sharing gains another 100, extra points will be given if the prediction turns out to be correct. In total, the user is able to gain a maximum of 200+α points.

How to store points

Four ways to store points:
・ Prediction 100P
・ Share your prediction to SNS 100P
・ The prediction turns out to be correct ???P
・ Invite your friends from LINE 100P

100 points will be rewarded for inviting each friend, inviting actively seems to be a profitable deal.


There is a ranking system inside 4CAST. Users can check the ranking and learn about their own position by tapping the trophy icon on the bottom of the screen. Users of the top 100 are always displayed.
Currently, the top ranked user owns 200,000 points. I have actually tried the system, and earned 3,000 points in thirty minutes.


Mypage contains functions including settings, wallet address, and is able to exchange points for LINK. Now it is possible to exchange 50,000 points for 1 LINK. It might seem to be a large amount of points at first glance, however it is not a number that cannot be reached.
This is my mypage site. I have 7,000 points right now, yet I haven’t spent much time on it. I am planning to collect points in a slow and steady manner.


On the whole, the process of prediction is unquestionably easy, and can win points at the same time. The whole system is extremely simple and easy to grasp even for a child altogether. It might take a little bit of time to get users to the stage of exchanging LINK, however it is still worth trying in your spare time.
