I am not particularly good at predicting the future, but I was having a lot of fun creating markets and watching my net worth tick up as people traded. It was good incentive to think hard about what would drive trading and traffic.
A month from now, will I think that the unique trader bonus is as satisfying?
It's obviously 100% subjective but IMO they are not as satisfying, it's probably more profitable in small markets, but the fee made it interesting for the "stock market" side of the platform, you'd price in the fee in your prediction, now if the market isn't super active you can always liquidate your position at no loss (which is good I guess because the daily bonus is ridiculous now so it's really hard to get mana liquidity outside the USA)
