ビットコインは18歳: オリジナルの反抗者は成長したか?

Bitcoin has officially reached its 18-year milestone since Satoshi Nakamoto published its original whitepaper in 2008. Over nearly two decades, the network has transformed from a niche cypherpunk project into a multi-trillion-dollar institutional asset class. However, this milestone arrives during a turbulent era marked by sophisticated AI-driven cyber threats and rising quantum computing concerns. The recent historic exchange hacks further highlight the operational vulnerabilities surrounding the broader ecosystem in which Bitcoin trades. Despite these persistent security and structural challenges, Bitcoin continues to consolidate its role as a decentralized macro hedge and core alternative financial infrastructure.
