Not great for a coin like Redstone when they have this kind of announcement on their trading page on Binance, a 400% increase in supply (this announcement has since been removed from the trading page). In general shorting launchpool coins is free money since so many whales get huge allocations for free by farming on Binance Simple Earn with BNB and can dump on a zero cost basis. The only exception to this I saw was Usual coin which pumped for a while after launchpool finished.
