Layer 2 of any blockchain should only invest in tokens of the original blockchain.
For example: There are many Layer 2 of Ethereum being built, so you should only invest in ETH.
If investing in L2, you need to consider the vision of that L2, like OP can completely invest because OP builds something much more macro than L2, Super Chain.
And if L2 promotes technology that readers absolutely do not understand, cannot implement, and has no users (up to now), then in general it is still in a state that cannot be escaped.
