Like Bitcoin, Ethereum is a decentralized, peer-to-peer digital currency. It means there is no central authority that controls it. It all started in 2013 when Vitalik Buterin, a 19-year-old whiz kid programmer (et al.), proposed to create a digital currency with a shorter block time than Bitcoin. With Bitcoin having come to birth four years earlier, the crypto talk was already in the air. So, Vitalik's idea was crowdfunded faster than anyone would imagine, and the Ethereum network went live two years later (2015), with well over 70 million coins.
The headquarters of the company behind Ethereum is in Ezugi, Switzerland. The crypto experienced exponential growth, and it is now available in at least 110 countries, as of 2022. It is the second biggest crypto after Bitcoin. In live dealer casinos, Ethereum supports both deposits and withdrawals.
