It is the first decentralized blockchain. It has gained a very rapid price value since 2017 and suddenly attracted the attention of all cryptocurrency users. But today the price is very low. Later, it reached a very high transaction volume and number of users. In fact, so much transaction volume grew that LTC founder Cardano published many statements. Because it approached just behind Ltc and even approached the market volume of Ltc. And it has surpassed LTC in transaction volume today. Yes, you didn't hear it wrong!
Cardano (ADA) consists of two stages: the payment screen and the control layer. My favorite feature is that you can do transactions without identity approval.
Ethereum is the leader in smart contracts. Cardano offers such advanced smart contracts that there is a risk of losing Ethereum's leadership to Cardano. Because Cardano, which closes the missing points in Ethereum's smart contracts, is forcing Ethereum.
In mining, BTC and ETH provide a great advantage in electricity usage by using the Cardano PoS system while doing electricity-based mining. Now ETH has switched to the PoS system. But the bad thing about PoS is that the more coins you have, the more you earn.
