I'd go with Polygon ($MATIC), the hottest L2 right now, and has a growing community and startups building within its network.
Terra ($LUNA) as well. Has a good long list of supposed projects that will do airdrops which means, people will seek out to hold this coin. More people holding = price increase.
If you want to get into the rumored airdrops, but want a cheaper option, I'd go to Cosmos ($ATOM). In the same principle, people want to hold this coin to be eligible for a bunch of project on it doing future airdrops.
And yes, before you ask, airdrops are considered profit.
Good pick all through, lately matic network has been experiencing a lot or network pressure as a result of nft games on the network, that ha been causing the network to be supper slow and a little high trans fees, but yeah, that's a project to watch out for, good for long term hold no doubt,
luna is a must have, beside airdrops the project is worth holding because of its numerous qualities, and yes holding luna and interacting with the network gives you the opportunity to receive airdrops from some projects on the network, luna ust staking gives good apy for a stablecoin, good choice for this period.
