In Defi Lllama, you can see some projects or platforms under Injective Protocol right now. As I can see, there are still a few of them there.
So for me, it's worth to try on any platforms here for sure, I highly suggest to verify each platform that they are legit and they still don't have yet released any altcoins.
Interactions with new platforms, new smart contracts, must be done with new wallets.
If using (not new) wallets, with big fund inside, to interact with new platforms, new smart contracts, people will put their wallets at risk and they can lose funds in these wallets. If fund is big, like all money they have, it's terrible.
Trying with airdrops is good, like trying lottery tickets but don't risk your funds with it.
