Can US citizens use bit com?

Could you please clarify for me if US citizens are permitted to utilize the services offered by Bit.com? I'm particularly interested in understanding if there are any restrictions or limitations in place that might prevent individuals residing in the United States from accessing or trading on this platform. Additionally, I'd appreciate it if you could provide any relevant information regarding the legal status of cryptocurrency trading in the US and how it might impact the ability of US citizens to use Bit.com. Thank you for your assistance in this matter.
