Just like his co-founder Gavin Wood, Charles Hoskinson went on to do his own thing after developing Ethereum. With Cardano, which hit an all-time high in August this year and currently stands at a $44 billion market capitalization, Hoskinson aimed to develop a more scalable, secure and efficient alternative to Ethereum. Cardano was at some point the “third coin” in cryptocurrency, the rotating coin that is the third biggest by market capitalization after Bitcoin and Ethereum and thus, in some respects, the one that competes most closely with them.
