Yes, you can earn from Launchpad but it depends on what project you are participating that is why you need to always DYOR before participating in Launchpad and launchpool it requires investment to stake before you can earn some rewards but even if you earn rewards from participating it still depends on the project if it's worth staking.

Are you trying to promote this project named GEMs I can't seems to find this on Binance or you might be using a different exchange?
I tried to check it on Binance and OKX but there's no project called GEMs?
