In this regard, some sites are more advance and secured than others and the credibility of its team not questionable hence, running a KYC on a trusted exchange isn't a bad idea. You've just got to enroll for a smooth running of business. Binance is okay and I can recommend them to anyone but, its always up to you.
Thats right and besides kyc is really mandatory to some exchange to abide the law of their country. What im just worried is what if the security got hack? do they have the enough security to hide those information? Privacy is really an issue nowadays.
