Don't get too FOMO, there are thousands of DAPPs out there in cross-chain activity. Not all new projects promise success. I remember Ethereum also has thousands of tokens and most of them are junk.
Every project takes time to mature. Currently, I only see Solana as the most sought-after Blockchain by the community. SAM has up to $900 million raised to grow Solana ecosystem. So prioritize the present.
Cardano is making lingo, I'll wait and see how fast developers will develop compared to other blockchains with their lingo.
