Bitcoin has surged past $100,000, marking a historic milestone in its journey from a niche asset to a mainstream financial instrument. This price surge is attributed to several factors, including macroeconomic conditions, technological advancements, institutional involvement, and supportive policies, particularly from the US. The US government's shift towards a crypto-friendly regulatory environment, including the introduction of the 'Digital Assets Framework Act', has played a crucial role in Bitcoin's mainstream adoption. The rally reflects a broader global economic and policy shift, with Bitcoin increasingly seen as a strategic reserve asset. The US has introduced tax incentives for long-term Bitcoin holdings and invested in blockchain infrastructure, enhancing Bitcoin's security and sustainability. Furthermore, Bitcoin's fixed supply and its role as a hedge against inflation and geopolitical instability have contributed to its appeal as 'digital gold'.
