Hello, I am a cryptocurrency investor living in the UK. I am interested in using KuCoin as my trading platform, but I am not sure if it is legal and operational in the UK. Could you please provide some information about this? I have noticed that KuCoin offers a wide range of cryptocurrencies and trading options, which makes it very appealing to me. However, I am concerned about potential legal issues or regulatory risks involved. Could you also advise me on the necessary steps to ensure that I am trading legally and safely on KuCoin? Thank you for your help!
