The idea that $SPS will lead the game is misguided imo. While it's true that if SPS goes up, it likely would attract more people (which would lead to a drop off in the amount of SPS each player would get), SPS is unlikely to lead the game. SPS reflects the game economy. It will be dragged higher or lower by the game economy, not lead it. This is one of the many reasons I've always said we need to deal with cards first. Cards are by far the biggest asset in the game based on market cap. They are bigger than SPS, DEC, licenses, and land put together. If cards are a money hole, it means the economy is broken and SPS isn't going to ignore that and move independently.
It is possible for a unique SPS event (like SPS getting listed on Coinbase) to spike the price independent of the game. But even that would likely end up being a disaster for the game. With the flywheel, SPS is designed to track with player demand, not investor demand. The higher SPS goes, the less of it players actually need in order to get the game's transactional token, which means price needs to track player demand in order to be functional. SPS getting ahead of the game would incentivize a euphoria filled flood flood of assets like rebellion packs and DEC, and then likely make it so the most valuable thing to do with SPS is to sell it all.
