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.
I don't think there is too much risk holding $BNB now, the token has been beaten badly recently, because of the FUD surrounding the exchange the price of the tokens has not seen much growth. To me BNB can easily do 10X from the current price, if people believe Ethereum is going to hit $10k, I don't see why BNB won't hit $2k in the next bull run, so holding BNB to participate in Launchpad and Launchpool is not a bad risk to take.
If BNB dumped I will continue to buy because it is one of the sound tokens on the market
