well if you are talking about staking BNB then they're all pretty much safe to invest, though the APY is low it does indeed gonna require you to invest some hefty amount to get meaningful rewards.
I've seen some people staking millions and get half millions as a reward I think thats good enough.
anyway if you are talking about investing in these project that are getting launched through binance launchpad, as I've seen so far, most of the project that get listed in binance whether having launchpad or not, usually always grow at the end of the day, though its not uncommon to see the price of the coin tanks first the first day of listing that to be expected, most of coin nowaday giving airdrops to people after finishing certain tasks, so these people gonna dump it but its also good opportunity for us that want to make investment because that usually where you will see the lower point of price you might never see again, so far the project like ENA, Wormhole and so on, even XAI and the likes are growing good, so its definitely worth a try.
