It was high time to improve Ethereum, but is it possible? So far, no one has been able to surpass the Ethereum platform.
Ethereum works just fine given the existing DApps adoption. Sure in the future it will need to solve the missing cap, scalability and transaction costs issues
One drawback is that transactions go on for a long time, but everything depends on the stock exchange, but in general I like it, I did not notice the minuses
