Top 3 cryptocurrencies by technology:
1. Ethereum (ETH)
Ethereum ranks 1st with an “A” rating. He brought smart contracts and DApps to the world of cryptocurrencies.
Ethereum is set to move to Ethereum 2.0, which will use Sharding technology to solve the scalability issues that have plagued Ethereum, especially during 2017 when large numbers of users clogged the network with transactions.
2. Stellar (XLM)
Stellar ranks 2nd with a "B+" rating. Stellar is a cross between Ethereum and Ripple in terms of technology.
Stellar can be used to create DApps, issue smart contracts, and create new Eth-like tokens with a transaction time of 2 seconds and less transaction costs. This attracted developers who were concerned about Ethereums scalability issues. One example is Mobius, which decided to use an ICO on the Stellar network instead of Ethereum.
3. Cardano (ADA)
Cardano is a blockchain platform that is still in its early stages, but all developments have been vetted by a global team of scientists.
