As an investor I think it’s always best to be an early adopter, I think we all know that but the main reason I personally think we’ll see more projects (L1’s specifically) is because of the Blockchain Trilemma. Once you focus on security within your chain your other points tend to fall a bit (Scalability, and Decentralization) and vice versa.
My belief is that the world will work in a multi-chain fashion, and innovation will always try to build better/faster/cheaper technologies to take down the competition
