Yes #Binance is right. But I think, after the launching of Binance launchpad, people now have only one approach to farm $BNB and $FDUSD during the farming period and when the trading starts, they eventually sell it.
This procedure of sudden selling of the free coins dumps the price of the project and most of the people end up selling at low prices. However, those who bought at the higher prices OR those, who think that price will further go up will not able to sell their coins and end up converting it into #BNB
Therefore, I believe Binance must need to take some action on this. This is not the first time, we are seeing this behaviour but this pattern is same for all projects who launched on the Binance Launchpad.
