I am not sure if there is a relation about launchpads and about what story you've told us here. 
Is there anyone here that has made money from presale or Launchpad before?
Yes I did. They're not a lot but still it's a money that I have earned from it. There's not that much effort and it's like the typical promos that we get from exchanges. You deposit their native token or stable coin that they support in a period of time and you'll earn that token they are supporting which they will list soon.
