Bitcoin's dormant supply has reached 61%, indicating its growing role as a stable store of value akin to gold. This trend is driven by institutional investors who prefer Bitcoin for long-term holdings. In contrast, Ethereum's coins are moved three times faster, with a daily turnover rate of 1.3%, due to its active role in DeFi and staking activities. Analysts caution that Ethereum's high transaction activity could pose structural risks, especially in volatile market conditions. While Bitcoin's stability attracts long-term investors, Ethereum's dynamic use in blockchain innovation highlights its potential vulnerabilities.
