According to Miles Deutscher, there are 58 million fiat millionaires globally, while only 21 million Bitcoin (BTC) will ever exist, highlighting Bitcoin's scarcity as a valuable asset in the cryptocurrency market. This scarcity factor is crucial for traders considering long-term investment strategies in BTC. The actual circulating supply of Bitcoin is significantly less than 21 million due to lost or inaccessible coins, further driving demand and potential price increases. Traders should consider this supply-demand dynamic when planning their BTC trading strategies.
