Can US citizens use CoinW Exchange?

Could you please clarify the legal standing of US citizens when it comes to using CoinW Exchange? Are there any restrictions or regulations in place that prevent American users from accessing or trading on the platform? Additionally, are there any known security concerns or risks associated with utilizing CoinW Exchange for US-based individuals? I'm particularly interested in understanding if there are any specific steps US citizens need to take in order to safely and legally utilize the services provided by CoinW Exchange.
