Traders are increasingly purchasing Bitcoin and Ethereum put options, signaling a hedge against potential market declines. Following a wave of margin calls last Friday, investors are preparing for further volatility, with significant activity in options markets. Data indicates a notable buying of Bitcoin put options with strike prices of $115,000 and $95,000, expiring on October 31st, and a shift from buying to selling call options with a $125,000 strike price, expiring on October 17th. In the Ethereum market, traders are focusing on options with strike prices of $4,000 and $3,600, expiring on October 31st and October 17th, respectively. There is also a surge in buying put options with a $2,600 strike price, expiring on December 26th, reflecting bearish sentiment extending to year-end. Despite the recent market reset due to reduced leverage, Bitcoin faces resistance challenges before achieving new highs, according to market analysts.
