To be on the safe side, I would recommend you to go mainly on BTC and ETH, they're still developing new technology behind, given the success that they already had. And if you're a big toy collector as much as I am, you can go with this NFT that has a twist of augmented reality. It also has its own hardware wallet in where you can store you collectibles together with other major coins. Still, you have to DYOR on any coin nor project that you're getting into. By the way, I like how you're considering the tech behind the coin you're looking for and not just there for the sake of getting profits.
