Forbes: Ethereum supply growth rate has been slower than Bitcoin since September 2022 merger

Odaily News For years, Bitcoin has been hailed as "digital gold," but in recent years, Ethereum has quietly surpassed Bitcoin in one key respect: supply expansion. Since the merger in September 2022, Ethereum's supply has grown at a slower rate than Bitcoin, challenging the long-held assumption that Bitcoin is the best form of sound money. Unlike Bitcoin's fixed 21 million BTC cap, Ethereum is designed to be adaptable, allowing its supply to expand or contract based on network activity.
While Bitcoin ensures absolute scarcity, Ethereum is more adaptable and flexible, able to adjust to market conditions. If sound money means supply growth, it has unexpectedly surpassed Bitcoin in this regard in recent years. (Forbes)
