Is Bitunix legal in the US?

Good day, I've been hearing a lot about Bitunix recently and I'm quite interested in it. However, I'm a bit hesitant to invest in it without fully understanding its legal status in the United States. Could you please clarify if Bitunix is indeed legal to use and trade in the US? I would greatly appreciate it if you could also elaborate on any potential legal risks or regulatory concerns surrounding its operation in the country. Thank you in advance for your assistance.
