Joshua Lim, co-founder of cryptocurrency broker Arbelos Markets, said the Bitcoin derivatives market on the Chicago Mercantile Exchange (CME), a favoured venue for established, traditional institutional players, has experienced its busiest days recently. Data shows that the November BTC call option was worth more than $350 million in nominal terms over the past week, with a break-even price of around $79,300 at expiration at the end of November, meaning these traders expect to profit from the rise in BTC prices next month. Joshua Lim said: "This could be a good sign that liquidity in the crypto derivatives market will continue to grow as the asset class matures."
