First of all, thanks for your support. We appreciate it. For the brain power:
You do not get STX for winning the prediction, you recieve brain power
the "Sun Tzu" version is completely risk free, meaning that you are able to deposit and use your real STX for predictions.
Whether the predictions are won or lost, the STX is returned to your balance.

Because of this current risk free implementation, instead of winning STX, you are winning brain power (BP)
The brainpower is added up in order to score/place you in the tournament leaderboards.

The predictions that have a yellow ribbon stating "win Real Tokens!" will earn you a portion of the prize pool stated on the prediction itself if predicted correctly
