So far, even though you say that BNB is a centralized coin, there are still several exchange sites that can be used to erase traces of cryptocurrency transactions. Whatever form of coin network is used, everything can be done. In cases like that, if CZ does it well and correctly, then no one realizes that he has done it.
CZ is a common scammer who blows dust in the eyes by touching on topics about "
security/future of cryptocurrency etc." He knows exactly what he's doing + manipulates asset themes where he can maximize his profit. Investigators are yet to investigate who he handed
BNB to when its price was yet to be formed. + It's far from clear how his personal will end. He could go to jail with no problem.
P.S. Don't invest in only one project. Diversify your assets. In case of
BNB scam - it will not be easy. Not to mention cases of fraud within the network itself, in transfers, etc.
