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.
