According to @ItsDave_ADA, only three of the current top-10 cryptocurrencies—Bitcoin (BTC), Cardano (ADA), and XRP—enforce a hard cap on total supply. Bitcoin has 19.9 million of its 21 million maximum BTC already in circulation (94.6%), Cardano has 35.3 billion of 45 billion ADA issued (78.5%), and XRP has 58.6 billion of 100 billion XRP in the market (58.6%). The remaining major cryptocurrencies do not have fixed supply limits and can increase token issuance, impacting scarcity and, by extension, long-term price stability. For traders, understanding which assets have a capped supply is critical for assessing inflation risk and potential value appreciation, especially during periods of heightened demand. These figures highlight the importance of tokenomics in cryptocurrency portfolio management and market positioning (source: Twitter/@ItsDave_ADA, May 16, 2025).
