Consider it as a safe airdrop where you have to make a deposit for a short period of time. Or earning easy few dollars in few hours for doing nothing (if you have BNB on Binance).
Actually for those who bought bnb at very low price this can be considered as free money always when launchpad and launchpool arrived at binance. But if they are buying bnb at high price and join theres a tendency of loss when bnb go down but it will always go up since many have like binance launchpad to spot new projects and keep joining.
