Bitcoin Whitepaper Turns 18 As Mining Costs And Quantum Risks Challenge BTC

Bitcoin marked 18 years since its whitepaper appeared on October 31, 2008, while BTC traded near $78,000 on November 1, 2026. The cryptocurrency commands a market capitalization of approximately $1.57 trillion, despite trading well below its 2025 record. However, declining mining rewards and future quantum computing threats present two major challenges for the network. Satoshi Nakamoto introduced Bitcoin through a technical paper outlining a peer-to-peer payment system without central financial intermediaries. The design capped supply at 21 million coins and offered users an alternative to conventional monetary systems.
