Be careful of anyone claiming to be Binance because they don't have Nigeriams Binance or whatever the name may appears, we have Binance US ad Binance global, there are Nigerians working with Binance from their head office, they have maybe some representative if fee in Nigeria but am not sure, if you come across any website claiming Nigeria Binance then check them well because rhey might be scammers operating on a cloned website to impose Binance.
Always lauch into a website from their original web address and if you don't know how to identify one, always ask others you think are reliable to help you out, they are not only attacking Binance but many other reputable organization and industries suffer their attacks of this manners.
Binance is a global cryptocurrency exchange so at that, many scammers will want to take advantage of the popularity of the name to be able to scam unsuspecting Nigerians, this is one such case and I guess the victim whose 1 million dollars is held in that scam exchange will not be the only victim, we may have some other members of the public who may be afraid to speak out, so I suggest the Sec should order for the arrest of those behind that scam.
Nobody is scamming using the name of Binance though — at least not "Binance Nigeria Limited." Have you read this piece? https://www.mariblock.com/exclusive-inside-the-nigerian-secs-recent-circular-on-binance/
