Hello! Thank you very much, everyone, for the responses!

I've continued investigating, and it looks like a scam. Initially, I was surprised because the information came from a close friend who confirmed that he was selling small amounts of Tether and receiving deposits in the bank.

I performed a whois lookup on the domain, and it's from late 2023, the first red flag. That's why it's not indexed, and there's no mention of it anywhere. When I asked him where he got this exchange, he said a person from a crypto channel on Telegram contacted him—second red flag. This person has no references beyond the Telegram channel and is asking him to invest more money while urging him to keep the operations secret.

I believe it's the kind of scam where they build trust by letting him make esmall withdraws to make him invest a huge amount of money, and then they disappear.

I discussed all this with him yesterday, but he really wants to believe that it's not a scam. Let's see how it turns out.

P.S.: I'm not my friend xD
