Tom Lee: BitMine has now become the world's largest Ethereum treasury and the largest single holder, owning nearly 5.78 million ETH. Bitcoin exposure: He chooses to directly hold MicroStrategy (MSTR) stock to benefit from BTC's price gains, rather than using BitMine to accumulate BTC directly. Ethereum reserves: The reason BitMine's treasury is built around ETH is because Ethereum's capital structure is simpler and more straightforward, making it more suitable for long-term asset accumulation by enterprises.
