According to Paolo Ardoino on Twitter, the concept of 'ultimate scarcity' refers to Bitcoin's (BTC) finite supply, which is capped at 21 million coins. This scarcity is a fundamental factor driving Bitcoin price movements and trading strategies, as traders anticipate reduced available supply over time, potentially leading to increased market demand and price appreciation. Ardoino's statement reinforces the narrative that Bitcoin's limited supply differentiates it from fiat currencies and other digital assets, making it a key consideration for traders seeking long-term value and volatility-driven opportunities (source: Paolo Ardoino, Twitter, June 20, 2025).
