After what Binance has done for past 6 months, this will be no big deal for them!
But the important thing is that this manipulation is not recommended for a big exchange like this. A lot of people lost a lot of money because of matic growth and they lost everything after 1 hour. This may be due to CZ and his team manipulating it, because previously the data showed that there were a lot of people making Long orders and the Matic dump would bring a lot of profits to them. I think Binance is not really a good exchange anymore, they are in a position to make the speculators lose more money.
