It seems that this site is a scam. I've been using it for some time now for small purchases (less than $100). However, their support has been extremely unresponsive. Recently, they froze around $500 in my account on their platform, and I'm unable to withdraw it or exchange it to BTC. Despite reaching out via email and using the chat option on their website, I haven't received any response from their support.

I strongly advise avoiding this site at all costs!
