I already participated in the Stride airdrop where you just need to liquid stake your TIA tokens there. Liquid stake your TIA to get stTIA tokens, hold it and you will get free daily STRD tokens.
If you still have TIA then at least try to participate in that one if you want to 
I currently prefer Atom coin as most projects focus on it. I also hold the majority of these coins. Regarding TIA, I made a mistake when I sold the asset at $2 and now regret it, missing out on the airdrops for this coin. I also participate in the airdrop for Stride, although the amount is small.
We all make mistakes don't worry. I also made one in the past, and I learned from it already.
With the recent events that are happening with TIA, it already came to a point where my total allocation with ATOM, and TIA are almost the same. Maybe it's because of the fact that there are many new projects that are integrating the new feature of TIA which is the data availability, and it's modular blockchain feature. Because of that, I expect that many projects will airdrop their token to native TIA stakers.
Speaking of staking, the Dymension mainnet is live already, and congratulations to us who are eligible for that airdrop. I got a small amount of DYM tokens for staking ATOM only at the time of snapshot which is kind of unfortunate. Well, it's free money, and I expect more in the future.
