OpenAI has seen a significant leadership shift with the stepping down of CEO Sam Altman, leading to the appointment of Mira Murati as interim CEO. This change has had a ripple effect on the cryptocurrency market, particularly impacting Worldcoin, whose token value dropped notably. As the AI and crypto communities look towards OpenAI's next steps, Bitcoin's market is entering a potential pre-bull phase in anticipation of the halving event and possible ETF approvals. Meanwhile, Polkadot is undergoing transformative changes under new CEO Fabian Gompf, focusing on developer accessibility and decentralized governance, alongside a substantial grants program to foster growth within its ecosystem.
