Like their L1 counterparts, L2 protocols generally have their own native token, which serves as an incentive to use the network. As an investor, I view a layer 2 as an investment in the infrastructure that allows greater access to the main room, while providing space for developers to build new and useful things. And so even if I don’t know what those useful things are yet, I know that more levels and doorways are needed in the building itself. Knowing that, I want to invest in the materials that will provide the new infrastructure.
