$BTC ! Oh! Now we have arrived at the brain behind web 3!

**\$ETH** or Ethereum, the second largest cryptocurrency after Bitcoin, but many consider it "more important" in terms of technology!

Here are the highlights:

* **The transition to Proof of Stake (PoS)?** Done, and the network became more efficient and eco-friendly!

* **DeFi and NFTs?** They are all built on ETH

* **The future?** Very strong with continuous updates like Sharding to increase speed

**Its price today?** It fluctuates, but big investors consider it gold 2.0 for smart applications!

And if you are thinking about investing in it, focus on the projects that are built on it, not just on the price itself.
