I have noticed a trend where people tend to wait until the last second in order to dump a massive amount of points into a prediction. I understand that this is part of the risk, however I frequently get invested at a low chance of success just to have someone else drop 4~10x the entire result pool I just entered. I agree with not allowing people to withdraw or swap, but it just doesn't feel good to suddenly risk 10k or 50k for a mere 1.05x payout. I propose two solutions:

First option is to add a toggle to the prediction creation procedure that veils the total contributed points until after betting has stopped, (Post maybe the % or the highest bettor per side, but not the cumulative total, highest bettor's bet, or ratio payout)
Second option is to add a [Max Bet] button of something like 10,000. Where people can bet up to 250,000 still, however it requires hitting that button 25 times so other bettors have an opportunity to see the ratio change over time rather than all at the last second.
