If this was not removed from bestchange immediately after your very plausible allegations of them being a scam, then I don't think that bestchange should be referred to as a credible source of information for exchanges at all. It is unprofessional at best for them to do this and not consider the position of clients.
Anyhow, KYC/AML is something that is cited by a ton of exchangers, especially on big transactions that it has become a routine honestly.
The takeaway here, if nothing else, is that if you're dealing with these types of sums of money, just don't risk it and use a normal exchange, like Binance, which give you around the same in daily withdrawal limits anyway for unverified accounts.
Bestchange is not an exchanger, it is just a monitoring of exchange offices. When making an exchange, everyone should understand all the risks that may arise as a result of the exchange. The fact that the money was returned in full, this is the merit of bestchange.
Can you bet your reputation that Binance will never become a scam? Personally, I can't say that what is reliable today will not be a scam tomorrow. The result is important, how the problem was solved.
I think it's time to close this topic.
