WARNING:
This site, the exchange-fast.top does not have https
It has no impressum.
A Whois call shows that the owner of this domain is hidden behind privacyguard.org
Its not clear who is behind that,
and I would never ever trust this site to send coins or funds there.
To me this looks like a SCAM or at least, its not a legit exchange.
Be warned...
I think what you inform, remind everyone to always be careful, worry that is also the right thing to do for anyone, including me, because there are now many fraudulent sites that provide something that is sometimes unacceptable to reason healthy. but it turns out there are also many people who are deceived, because they want a very large and fast profit, which is clearly very unlikely.
