Ark Invest CEO Cathie Wood expressed her preference for Bitcoin over Ethereum during an appearance on The Master Investor podcast. Wood highlighted Bitcoin's status as a rules-based global monetary system and its distinction as the only Layer 1 blockchain that has never been hacked. While acknowledging Ethereum's foundational role in decentralized finance (DeFi), she noted the increasing competition it faces from Layer 2 solutions. Despite her preference for Bitcoin, Wood revealed a growing interest in Ethereum, evidenced by her recent investment in BitMine shares, which indicates a strategic increase in her exposure to Ethereum-related assets.
