According to Odaily, Bitcoin has long been regarded as 'digital gold,' but Ethereum has quietly surpassed it in a key area: supply expansion. Since The Merge in September 2022, Ethereum's supply growth rate has been lower than Bitcoin's, challenging the long-held assumption that Bitcoin is the best form of sound money. Unlike Bitcoin's fixed cap of 21 million BTC, Ethereum's design is adaptable, allowing its supply to expand or contract based on network activity. While Bitcoin ensures absolute scarcity, Ethereum offers more adaptability and flexibility, adjusting according to market conditions. If sound money implies supply growth, Ethereum has unexpectedly outperformed Bitcoin in recent years.
