Jack Mallers, CEO of Twenty One Capital and founder of Strike, has expressed confidence in Bitcoin's continued value increase, citing its scarcity as a key factor. Despite concerns about limited supply, Mallers highlighted that demand from companies like Metapalent, Marathon Digital, and GameStop is pushing prices upward. He emphasized that Bitcoin's fixed supply will lead to higher prices as competition for the remaining coins intensifies. Mallers also pointed out that while demand from entities such as ETFs and the U.S. capital market will persist, they will have to pay significantly more to acquire Bitcoin due to its unchanging supply.
