Can US citizens legally use KuCoin for cryptocurrency trading?

US citizens can legally use KuCoin for cryptocurrency trading, although there are certain limitations and considerations to bear in mind. While KuCoin is an international cryptocurrency exchange not based in the United States, it provides services to US residents. However, due to the strict regulatory environment in the US, particularly with respect to securities and anti-money laundering regulations, KuCoin does not offer the same full range of services to US customers as it does to users in other countries. For instance, they might limit or exclude access to certain tokens that may be classified as securities by US authorities. Users from the US should also be aware of their responsibility to comply with IRS rules concerning the reporting and taxation of cryptocurrency transactions. Therefore, while US users can trade on KuCoin, they should exercise caution and ensure they understand and adhere to all relevant laws and regulations.
