Wu said he learned from GreeksLive that today’s large-volume bullish options trading for Bitcoin saw an explosive surge, with total trading volume of 25,766 BTC and a notional value of about $1.65 billion. Among them, Bull Call Spread contracts with strike prices of $70k/$72k expiring at the end of this month had trading volume of nearly 10k lots, becoming the main trading target in the market. Analysts believe that with only two weeks left until the end of the month, large purchases of 10% out-of-the-money call options indicate that the market is optimistic about the outlook for the second half of this month; however, since traders tend to choose Bull Call Spread strategies with relatively lower notional value, it suggests this is only a tentative dip-buying move. As the market has remained in low volatility for the long term, the likelihood of a modest rebound is increasing.
