When I just got into Bitcoin, for the first few months I used to sell my coins on those exchanges from Bestchange. Luickily I soon found the proper crypto trading platform, which operates legally and has much better fees than those sketchy exchange services. And not only they are criminal, a lot of them are also scams, they steal money whenever someone tries to move large sums through them - saw some stories in the Russian local board.
I still use exchanges listed on Bestchange because I cannot find one that would be easy to use, reliable and have the fees which are as low. I try to choose exchanges with lots of positive reviews, and I've never been scammed this way, but of course there are many exchanges there, and some of them might be scamming people or be used for illegal activities.
At least the e-exchanges are not the main stream ones. The fact that Binance played an active role against this type of fraudulence speaks for itself - Bianance will not tolerate such behaviour, and in fact no e-exchange should either.
It is interesting though that the law just managed to catch the gang given their dubious activities for nearly 2 years
Yes, I'm pretty sure they aren't mainstream, and I'm glad that Binance helped with the investigation. As for exchanges operating for 2 years, I don't find it weird because Ukrainian law enforcement doesn't typically get involved with cybercrime, not to mention that there's always a chance the criminals were bribing some police officers to ensure they won't get involved.
