The 4 advantages of Ethereum are now possible with many other blockchain platforms, like Tron or Cardano. To me, Ethereum plays the biggest role because it brings the concept of crypto closer to everyone, it is blockchain 2.0, when we think more about the highly customizable in smart contracts to make full use of blockchain, not just a platform that provides new means of payment.
We can realize this with the purpose of Vitalik Buterin with Ethereum to become the computer of humanity, allowing anyone to access, own and use crypto.
