Does XTB take US clients?

I'm curious to know, does XTB accept clients from the United States? I've been looking for a reliable and trustworthy broker to trade cryptocurrencies and other financial instruments, and XTB seems to have a good reputation. However, I'm unsure if they cater to US clients or if there are any restrictions in place. Can you shed some light on this matter and help me understand if XTB is a viable option for me as a US investor?
