In my opinion, i think Cardano and ETH are the most coin/token with the best technology in recent time.
Cardano.
The main aim of Cardano, a decentralized, open source blockchain, is to revolutionize smart contracts. The developers behind Cardano want to deliver a far more advanced smart contract platform.
Ethereum.
One of Ether’s most promising technological developments is decentralized applications (DAPPS). DAPPS are open source apps that serve up a high level of transparency, unlike centralized applications currently in use.
