BlockBeats News, on September 4, Greeks.live macro researcher Adam tweeted, "The market is currently in a clear downward trend. BTC's short- and medium-term IV has risen to 40%, and ETH's short-term IV has surged to 70%. The increase in short-term IV indicates that the market expects higher volatility this week. The decline in crypto-related stocks in the US stock market, especially the MicroStrategy series of stocks, is the trigger for this downturn. Historically, September has always been a month of weaker capital inflows, while the last quarter tends to see more abundant funds. Today's block trading volume of put options is also rising rapidly, with a total transaction amount of $1.17 billion, accounting for 30% of the day's total trading volume, showing that a defensive mindset has become mainstream."
