For BTC and ETH, narrative plays a major role in influencing prices in risk markets, and sentiment is an extension of narrative. The cryptocurrency market is no exception, and price fluctuations in the market may be caused by changes in narrative or changes in sentiment. Simply put, the price push of BTC and ETH depends on whether the market recognizes and accepts their stories, and whether these stories can be realized. However, once the story is told and there is no follow-up, the sentiment will also fall.
