Perfect predictions

Inspiration

People would hash some message ahead of time and reveal their prediction in the future to show their prediction or show off what they know. Although this method is cool, it's hard to track their track record and people can easily delete or ignore their past predictions. My site's predictions are immutable and makes monetizing predictions much easier

What it does

Allows people to create predictions with specific timeframe and automatically reveal it when time is up. It shows all past predictions and lets people pay to see someone's prediction before the actual reveal time. A good example is someone can claim they are good at trading stocks, but they often only show the highlights. My platform lets people build history and let them monetize through early reveal of good picks through early predictions.
