It’s been a stellar week for the digital coin Ether as its price hit an all-time high of over $3400 on Tuesday, extending its rally with gains of more than 300% this year. The coin has quadrupled in value since the start of 2021 and some experts believe there’s more to come. Ethereum is the world’s second-largest cryptocurrency and has seen a growth of over 320% from the beginning of the year compared to Bitcoin’s 98% – which is still very impressive.
