Once the new token has paid the listing fee, they are allowed to "promote" their project, which usually means posting a link to their server and relevant information, as well as posting an airdrop to be collected (no strings attached, just click a button and it goes into a user's tipcc custodial wallet).
There are some coins that don't make it, but there's no risk or investment for collecting, and you can find out a lot about a coin/token by how they handle their community in their own discord server. Also, you can still use your checklist of whitepaper/team/etc...
However, some projects limit that only the first 100 or 1000 people who enter the discord can get these short positions.
How to get this kind of consultation? Need to follow many projects on Twitter at all times?
I've only seen this kind of setup once, and the airdrop never happened and the server was deleted soon after. On any coin of substance that intends to stick around, the airdrops will be carried out over a time period defined in their whitepaper and to be distributed to as many people as possible so as to create a mass appeal. It's kind of like the old drug-dealer slang: "The first one's free."
And in discord, not only the project team will distribute, but you'll find that there will be key players in the community that will take an interest in the coin and also distribute it in order to boost interest in their investments as well.
