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).

According to Crypto Rover, the total supply of Bitcoin is mathematically capped at 21 million coins, making it impossible to create additional BTC beyond this limit (source: Crypto Rover on Twitter, May 16, 2025). This absolute scarcity is enforced by Bitcoin’s protocol and decentralized consensus, ensuring no central authority can alter the supply. For traders, this hard cap underpins Bitcoin’s value proposition as a deflationary digital asset, often leading to increased demand during periods of rising adoption or macroeconomic uncertainty. Understanding this fixed supply is crucial for anticipating potential price movements, especially as halving events further reduce the rate of new supply entering the market.

According to @AltcoinGordon, 80% of all US dollars in circulation have been created in the last five years, while Bitcoin maintains a strict supply cap of 21 million coins (source: Twitter, April 28, 2025). This stark contrast highlights Bitcoin's scarcity as an asset compared to the inflationary nature of fiat currency, a factor increasingly cited by traders analyzing long-term Bitcoin price potential and inflation hedge strategies. Many market participants are using this data point to inform their trading decisions, particularly in light of ongoing concerns about currency devaluation and the search for hard assets (source: Twitter, April 28, 2025).
