I'm a bit confused about the legal status of cryptocurrency in China. Can you provide me with some clarification? I've heard different opinions and rumors about it, but I'm not sure which ones are accurate. Is it legal to own and trade cryptocurrencies in China? Are there any specific regulations or restrictions that I should be aware of? I'm particularly interested in Bitcoin and Ethereum, are they legal in China? I'd appreciate it if you could provide me with some detailed information and clarify any misunderstandings I may have. Thank you!
