If you're interested in the biggest cryptocurrencies around, you must have heard of Cardano (ADA) before. Considered one of Ethereum's (ETH) biggest competitors, it got a lot of talk in 2018. Find out more about this altcoin in our comprehensive guide with Cardano price predictions. The goal of Cardano is to build decentralized applications (dApps) and smart contracts. It works very similar to ETH, but Cardano and ERC-20 coins are not the same type of tokens. With ADA, it should be possible to support a large number of transactions per second and be compatible with other blockchains. The goal is to get rid of all the unnecessary layers that are applied to blockchains, similar to the Lightning Network created for Bitcoin (BTC).
