This practice can create sudden price drops and increased volatility, catching retail traders off guard. Traders should monitor on-chain data and social media activity for large wallet movements after such posts to mitigate risk. This highlights the importance of skepticism towards influencer-driven signals and the need for independent technical analysis in altcoin trading.
