Is HTX legal in the US?

Good day, could you please clarify for me the legal status of HTX in the United States? I've been hearing about this cryptocurrency and its potential for investment, but I'm unsure if it's legally allowed to trade and own within the US jurisdiction. Could you elaborate on any regulations or restrictions that might apply to HTX in the country, and whether or not it's considered a secure and viable investment option for American citizens? Thank you for your time and expertise in this matter.
