Well, just holding Linea will open up further rewards opportunities, mostly in other tokens; some from Consensys and some from protocols that we are aligned with. MetaMask and Linea are cooking somETHing together to make this happen. Together we are all bootstrapping the Linea Token Economy. Holding LINEA tokens signals that you are a Linea community member and are likely engaged in productive Linea Economy activities: building, liquidity provision / staking, using, collecting, .... So if we notice, at some date in the future that you've held n LINEA tokens for m days, that just might lead to another token landing in your account. And if n and m are larger numbers your account might receive a larger reward. Rinse, repeat.
