The closer we get to March 27, the greater the volatility of BTC. This is because a large number of options are set to expire on that day. Among them, 120,000 call options and 70,000 put options. Most of the strike prices are concentrated in the $70K–$75K range. These days will see repeated tug-of-war, with the price being 'pinned' within the range and oscillating back and forth.
