According to TechFlow, Lin Chen, head of Asia-Pacific business at Deribit, said that in today's largest Bitcoin block options transaction, an investor bought a $62,000 call option at the end of the year and sold a $100,000 call option at the end of the year, totaling 400 BTC and paying a premium of $2.334 million.

This move shows that the investor is bullish in the long term. By buying and selling, the cost is reduced and leverage is added. If the price is above $69,300 at expiration, it will be profitable.
