Fake Crypto page. They contact victims on flippa.com, pretend to be interested to buy a domain offer for high price and ask you to sign up in the (fake) crypto platform bitrichex, where you get a fake payment in your account. You can't withdraw the payment, instead they ask you to "deposit" 1000 $ to unlock the account. I found a report in trustpilot about bitrichex scam via flippa to bitrichex reported by an author just 18 hours before me, so this seems to be a new, current fraud scheme.
