These scams are regularly found on Telegram, and scammers appear with tempting offers. I don't know why you agreed to trade based on this stranger's offer, Telegram is full of scammers. When I first saw this website I thought it was a scam website. Because this inconsistency is seen in many things. This website was created not long ago, it is not easy to get an original website into full operation so quickly.
this is more than an obvious scam and I would say a fairly well-known method, although the OP proves that it is not known to everyone.
I can't help but ask a question, this time for the OP. why the hell didn't you get here before the whole trade started and ask for advice? why did you go into the whole thing so lightly without examining all the possibilities?
I hope you didn't lose too much money, the only thing you can do now is to forget about the whole thing.
That's the problem, they don't even do the small thing of posting here and taking advice before falling victim to a scam. As they are attracted by tempting offers, they prefer to keep everything confidential. But their thinking is the most effective for scammers, evidenced by the fact that the OP herself has fallen prey to scammers.
