The findings indicated that, at higher percentiles, investor sentiment had a positive impact on the Bitcoin market’s collapse risk. This might be due to positive sentiment causing investors to be more overly optimistic about the Bitcoin price, leading to irrational investment behavior and pushing up the price to unreasonable levels. In this process, liquidity was not the main influencing factor.Conversely, at lower percentiles, investor sentiment had a negative impact on the Bitcoin market’s collapse risk. Low sentiment increased the investors’ concern, panic, and pessimism, leading to greater downside risk in the Bitcoin price. Additionally, market liquidity played an intermediary role as investors might be more inclined to sell Bitcoin to reduce risk, thereby decreasing the liquidity.These findings held valuable academic and practical implications for understanding the price fluctuations of the Bitcoin market and investors’ behavior. Furthermore, it was also provided insightful information for relevant market participants.投資人情緒比特幣市場崩盤風險流動性分位數回歸Investor SentimentBitcoin MarketCrash RiskLiquidityQuantile Regression Analysisetd
