Odaily News According to Lin Chen, head of Asia Pacific business at Deribit, the largest BTC option yesterday was: a user bought a $40,000 put option at the end of November 8, and sold a $40,000 put option for March next year, totaling 1,275 BTC, paying a premium of $1.204 million. Analysts believe that investors seem to have locked in $40,000 in "insurance" for the end of the US election, but the price they paid is that if the price falls below $39,000 (the break-even point for selling put options) at the end of the year, they will face losses.
