Ethereum is the most well-known altcoin, and it’s much more than just another cryptocurrency for many investors and enthusiasts alike. And experts say it could grow in value by as much as 400% in 2022. Ethereum’s native token, Ether (ETH), has grown immensely in value since its creation. Launched in 2015 by computer programmer Vitalik Buterin, Ether has increased in price from $0.311 at its 2015 launch to around $4,800 at its highest late last year — with plenty of volatility along the way.
