Why not? Cardano also supports smart contract and continue to build to support growing ecosystem its one of the tough competitor of eth for now, it only needs mass adoption like Eth where most projects like defi and nft are created, more developers must use Cardano inorder for them to become as popular as eth, in terms of price potential I think ADA is a good investment to hodl for years like ETH, BTC if you see it price history ADA price increase exponentially from its ICO price $0.002.
