I choose the cardano based on their developer of the team which has good experience in cryptocurrencies.
The Cardano protocol was created by Charles Hoskinson, one of the co-founders of Ethereum. Cardano’s Bitcoin-like Settlement Layer (CSL) mainnet is live and it has a functional wallet for its built-in ADA cryptocurrency. It has also taken a different technical direction from other blockchains on several axes, like its Ouroboros proof-of-stake algorithm, its use of Haskell, and its focus on formal verification. While Cardano’s Computation Layer (CCL) is not yet live, the project has published long-term roadmaps, has shipped working software, and appears to have a growing community.
