Validating the between social media KOL and price involves several steps. First, collect data on KOL posts and corresponding market prices. Use sentiment analysis tools to quantify the tone and intensity of KOL messages. Next, apply statistical methods like Granger causality tests to determine if KOL sentiment precedes price changes. Additionally, analyze the volume and timing of trades following KOL posts to identify patterns. Case studies and controlled experiments can further isolate the impact of KOL influence. By correlating sentiment shifts with market movements, researchers can establish a clearer understanding of how KOL drives price.
