Bitcoin's market capitalization is approximately $1.8 trillion, making it the largest capital pool in the cryptocurrency sector, significantly outpacing Ethereum's market cap, which is about seven to eight times smaller at $230 billion. Despite this substantial market presence, 99% of Bitcoin remains idle and is not utilized within decentralized finance (DeFi) due to programmability and custody limitations. However, the DeFi landscape for Bitcoin has seen remarkable growth, expanding by 2,000% in 2024. Babylon is working on infrastructure that aims to leverage Bitcoin's $1.6 trillion security budget to enhance the broader blockchain ecosystem. Additionally, Elastos is at the forefront of this evolution, developing secure frameworks that utilize Bitcoin's security through merged mining. Critics, however, argue that Bitcoin's security model has fundamental flaws that require urgent attention, highlighting the ongoing debate about sustainability within the cryptocurrency space.
