Hi new to Launchpads.

I like to invest in new and upcoming projects at discounted prices before they release on the public market. How do I buy in these private sale rounds at cheap prices?

Which is the most reputable best smart contract platform that has its own launchpad that introduces new upcoming projects? Which smart contract platform launchpad verifies and audits all upcoming/new projects and its code to check whether the project is a shit/scam coin?

Otherwise when looking for upcoming new projects on these launchpads how do you filter out the shit/scam coins and instead invest in the good ones?

Which launchpads you guys use to get in early?
