Why China banned BTC?

Could you please elaborate on the reasons behind China's ban on Bitcoin? I'm particularly interested in understanding the perspective of cryptocurrency and finance professionals on this matter. It seems to be a complex decision with multiple factors at play. Could you possibly break down the key considerations that led to this ban? I'm curious to know how the risks associated with Bitcoin, such as energy consumption and financial instability, might have influenced China's regulatory stance. Additionally, I'd like to understand how the ban aligns with China's broader financial and monetary policies. Your insights would be greatly appreciated.
