$BTC as the pioneering cryptocurrency, has demonstrated resilience and growing institutional recognition. Its scarcity and decentralization position it as a digital store of value in the future. However, its volatility and the environmental impact of its mining are significant challenges.

For the future of cryptocurrencies, BTC could continue to be the main store of value, while other blockchains with greater scalability and lower energy consumption could lead in applications such as smart contracts and decentralized finance (DeFi). Interoperability between chains and clear regulation will be crucial for mass adoption.
