Even when Bitcoin reaches a market cap of $100 trillion, it may still be subject to volatility. Although its price may be more stable when compared to its current market cap, its decentralized nature and lack of government backing still makes it more susceptible to price fluctuation than other more established currencies. Additionally, the global nature of Bitcoin can lead to volatility due to changing economic and political conditions. However, as Bitcoin’s usage and acceptance continues to grow, its volatility could decrease over time.
