Ethereum is a blockchain platform that allows developers to build decentralized applications (dapps) and smart contracts. It is the second-largest cryptocurrency by market capitalization after Bitcoin, and has a large developer community and ecosystem of decentralized finance (DeFi) applications built on top of it.
If all large companies that issue stablecoins work on the Ethereum blockchain, then this ecosystem has a great future. But it is unlikely that if you buy Ethereum for $2,000, you will be able to sell it soon for $20,000. Ethereum is a more conservative coin for investment, I think that there should still be a price dump, but it will be difficult to earn large XX here.
