Who would send their documents and selfie and many more things they asked to site like this one?
I wouldn't trust them to refund your money even if you did send the things the are asking, and the risk of your documents ending up on some darknet market or being used by someone else for some shady activity is extremely high.
I'm quoting 1miau again
KYC is encouraging identity theft
Not saying Janyiah201 should procure fake identity information, just saying it could be a way to try getting those funds back. Assuming they do return the funds by just seeing some ID document, which of course makes no sense since it doesn't make 'criminal origin funds' suddenly 'non-criminal', but what do I know.
I've never used BestChange, but I find it very questionable that they allow exchanges to simply close claims like this. OP has obviously not been refunded, but OpenChange have now closed his claim 24 times without resolving it. Looking back through their previous ratings, there seem to be a number of other issues which have been closed without being resolved. BestChange therefore show OpenChange as having an unblemished 100% positive feedback, which is obviously not the case. Such a system allows any exchange to keep a perfect record so long as they are more determined than their victims, who will eventually give up renewing their claims.
Indeed; I got a positive impression of BestChange since browsing Bitcointalk, since respected community members wore the BestChange signature. But this case makes me hesitant to trust BestChange in general, in the future. If BestChange ratings can so easily be manipulated, it begs the question of what use that site even is.
