Ethereum is the second most popular cryptocurrency, which is considered the most real competitor of bitcoin. And all thanks to the fact that the ether has one important advantage over other altcoins: it can be immediately exchanged for dollars without the need to first convert to bitcoins (as in the case of other bitcoin-dependent cryptocurrencies). The demand and popularity of this digital currency is also associated with its unlimited emission. That is, theoretically it can be mined for a very long time. Ethereum is not just a cryptocurrency. The system is a decentralized platform for application development. And the more such applications work, the more stable the Ethereum project as a whole and the more expensive the cost of its tokens.
