China has officially declared all cryptocurrency trading, mining, and related services illegal, citing financial risks, capital flight concerns, and environmental impacts. This announcement reiterates the country's long-standing strict stance against digital assets, with multiple bans issued over the past decade. Reports indicate this is at least the seventh ban since 2013 and the 87th ban on Bitcoin specifically in the past ten years. While some sources note that China’s crypto ban dates back to 2021, the recent declaration reinforces the government's ongoing efforts to tighten regulations on the cryptocurrency sector.
