what happens to dex, especially Binance dex is often triggered by the pumps of their own dev and the whales just welcome it. There is no specific reason for money laundering, but this is more valid because they have the power to do it, I call it the quick profit mode. The interest of traders in Binance dex is different from the others with a slightly better volume day by day.
Well, money laundering is definitely out of question because even if they do they have too much risk of losing the value due to the volatility. I think it's just a usual price manipulation maybe the devs are trying to keep their coin alive by pumping their own coin because most of the coin in dex have low volume anyway so you dont need so much money to pump and they are trying this hoping that people will start to buy and they can then dump their coin afterward. I also couldnt see how whales profitting from pumping this coin anyway.
