If we look at the many L2 projects that have failed and abandoned due to not meeting the expectations of adopters and losing the trust of the community. Since they are basically launched based on hype alone, I also want to make sure that you are talking about this project
https://chainbase.com/ which will TGE in the next few days? if true then one thing this project will definitely do is implement a staking feature in order to survive.
Don't be FOMO and you should be able to monitor the activity first on the mainnet later, study carefully the roadmap and tokenomic, because this is quite important to measure the sustainability of a new project.
Not all projects are meant to survive in the long run. That's why, when you first learn about them, it's good to give it a try. After benefiting from it, you can move on to the next one. If you want to see it through to the end, you'll be very disappointed at what the project will turn out to be. TGE is soon. I wonder which exchange is best for me to deposit to. Do you mind sharing which one you'll be using?
