Odaily Planet Daily News: Investors are watching December 27, when $11.8 billion worth of Bitcoin options will expire, which could trigger significant price fluctuations in either direction. Nick Forster, founder of the decentralized options protocol Derive, pointed out that Bitcoin's volatility has remained stable over the past seven days, with an implied volatility of 63% for the next seven days and 55% over 30 days. "This tight consistency suggests that the market expects significant fluctuations to occur soon." Bitcoin has currently retreated from its high, and one of the reasons cited by market participants for the price drop is profit-taking. (Reuters)
