Odaily News Lin Chen, head of Asia Pacific business at Deribit, posted on the X platform that the largest BTC option today: someone paid a premium of $1.397 million and bought a call option of $85,000 at the end of March next year (expiration strike price), totaling 250 BTC. According to his analysis, this person is bullish on BTC in the long term and may have thought that this plunge was a good opportunity to build a position, so he directly increased his position.
