5. Cardano (ADA)
Cardano entered the crypto world a little later than most cryptocurrencies, but it stands out by using proof-of-stake validation early on. By eliminating the competitive, problem-solving part of transaction verification found in systems like Bitcoin, this approach reduces energy consumption, increases transaction speed, and has a smaller negative impact on the Crypto market.
The native token of the network, ADA, hasn't exactly had the greatest of moments recently, but it still has great promise in the months to come. According to statistics, Cardano has recently been one of the top trending green Cryptos in 2022.
Cardano might surpass other cryptocurrencies in energy efficiency as the transition to net-zero emissions picks up speed. With ADA, its native coin, Cardano, one of the popular green cryptocurrencies in 2022, also functions like Ethereum to facilitate smart contracts and decentralized apps.
Compared to other significant crypto coins, the growth of the Cardano ADA token has been somewhat subdued. The cost of ADA was roughly 1.5p in 2017. On October 3, 2022, it cost roughly 37p.
