As far as I know if something was wrong with Binance they clearly talked about it without any prolonging. And if CZ says that it is just FUD and nothing happened I believe him, because there was no cases when he lied.
LOL, you can't say that, they owned the business and normally a business would hide information if that affect their business negatively, they said it's fake but they are still doing an ongoing investigation on it. If people will complain, their result of investigation is not much reliable compared to the 3rd party company that should conduct an investigation to have a non bias result.
