From what I know, there are many platforms where we can find potential projects from a Token Generation Event (TGE). It's up to us to choose which platforms we use.
However, most of these projects are high-risk, and only a few can be said to have real potential.

Some of the examples I know are projects announced on exchanges well-known in this field, while others can be found on sites like airdrops.io, Telegram,
and other platforms I won't mention.
