I was just pondering whether it's possible to create a product for long and short positions based on KOLs (Key Opinion Leaders). By using objective data indicators like KOL influence and reputation, we could turn it into a candlestick chart. If you have high hopes for an obscure but promising blogger, you could go long; if you sense that a certain KOL is about to collapse or fade away, you could go short. Essentially, it combines the two products, Friendtech and Kaito. Technically, it's not an issue, and there are certain solutions for preventing cheating and inflated numbers. It seems feasible?
