Ethereum is another use-case for a blockchain that supports the Bitcoin network, and theoretically should not really compete with Bitcoin. However, the popularity of ether has pushed it into competition with all cryptocurrencies, especially from the perspective of traders. For most of its history since the mid-2015 launch, ether has been close behind bitcoin on rankings of the top cryptocurrencies by market cap. That being said, it's important to keep in mind that the ether ecosystem is much smaller than bitcoin's: as of January 2020, ether's market cap was just under $16 billion, while bitcoin's is nearly 10 times that at more than $147 billion.
Like other blockchains, Ethereum has a native cryptocurrency called Ether (ETH). ETH is digital money. If you’ve heard of Bitcoin, ETH has many of the same features. It is purely digital, and can be sent to anyone anywhere in the world instantly. The supply of ETH isn’t controlled by any government or company – it is decentralized, and it is scarce. People all over the world use ETH to make payments, as a store of value, or as collateral. The latest news about Ethereum mostly concerns the move to Serenity the last post-development phase of Ethereum as well as changing Ether mining’s concept from Proof-of-Work to Proof-of-Stake in order to reduce the power cost of the process.
