Bitcoin traders are making big moves as they place their bets on a dramatic surge in the price of the cryptocurrency. The focus has shifted to the $300,000 BTC call option expiring on June 26, 2025, which has garnered significant attention. With Bitcoin currently hovering well below this level, the out-of-the-money (OTM) call represents a high-risk, high-reward opportunity for those looking to capitalize on a major price increase by summer.

The June $300K call option has become the second-most traded option for the upcoming expiry, with over 5,000 contracts active and a total notional value of around $484 million. This surge in open interest highlights how traders are positioning themselves for a potential Bitcoin price explosion.

A call option gives the buyer the right—but not the obligation—to buy Bitcoin at a set price of $300,000 by the expiration date. Because the option is far from the current market price, it is cheaper to buy than other more conservative options, and while the chances of hitting the target price are slim, the payoff could be substantial if Bitcoin reaches that level.

Spencer Hallarn, a derivatives trader at GSR, said that the growing interest in such an extreme call option reflects an underlying optimism about Bitcoin’s future. “It’s an opportunistic bet,” Hallarn noted. “With regulatory changes, institutional interest, and potential market movements, these high-risk options could become quite lucrative if Bitcoin rallies.”

This call option isn’t the first of its kind, but the level of interest it has attracted in recent weeks is unprecedented. June 26, 2025, is shaping up to be a significant date, with a notable amount of open interest accumulating in the $300K strike price, signaling that traders believe a major price surge is possible.

Furthermore, the covered call strategy is becoming increasingly popular among Bitcoin traders, where investors hold Bitcoin and sell high-strike calls like the $300K option to collect premiums. This allows traders to generate income while still holding onto their positions, hedging against potential volatility.

As the June expiry draws nearer, the $300K BTC call is quickly becoming one of the most talked-about contracts in the market. The options activity, along with increasing institutional interest in Bitcoin, has traders on edge, anticipating that this could be one of the most pivotal moments for the cryptocurrency this year.
