From memory, it was Edward Thorpe who first documented that this had to be a fraud, after being asked by a friend to investigate on a method to duplicate the returns. Thorpe first figured it out.
Years later, the CEO of Renaissance tried to duplicate Madoffs returns, and also gave up, telling his employees that it had to be a scam.
Eventually, Markopolis took a look into it. He is wrongly attributed as the person who figured it out. But... he stared himself in a movie production about the case, so he gets the glory I suppose...
So you think because of this story, it means that Binance is a fraud? So who do you suspect they defrauded?
Cant be going around pointing the finger just beause of a bed time story you heard....

. Been proved many times where Binance volumes come from.
