According to @Bitcoin on Twitter, the total supply of Bitcoin is permanently capped at 21 million coins, with no possibility of increase. This fixed supply model is a key factor in Bitcoin’s value proposition, contributing to its scarcity and appeal among traders seeking deflationary assets (source: @Bitcoin, Twitter). Traders should note that as the circulating supply approaches its maximum, potential supply shocks and heightened demand could increase price volatility. Monitoring on-chain metrics as the supply nears the 21 million limit is critical for trading strategies, especially as mining rewards decrease and long-term holders impact liquidity.

According to Tetranode, Bitcoin's security budget is a critical concern as it approaches four halvenings from now. The reduction in block rewards will necessitate a reliance on transaction fees to sustain miner incentives and network security. Without increasing transaction fees, maintaining the 21 million Bitcoin cap while ensuring network security presents a significant challenge. This transition period requires careful monitoring by traders, as any imbalance could affect Bitcoin's price and market stability.
