Cardano,Polkadot,EOS.AION,NEO,TRON,ICON.. who will be next?
The most interesting news in 2021 will be talking about the Ethereum ecosystem. If the launch of Ethereum 2.0 is successful and the launch of Phase 1 accelerates,
then the other coins will have no chance of even getting close to Ethereum.
Have you noticed that "Ethereum killers" are getting smaller every year?
I can relate to the this, EOS was regarded as ethereum killer ever since it was lunched, has a different features and hardly to understand, over the years some many altcoin coming out their respective features seems to have outsmart ethereum protocol but they all not getting their target.
Now, ethereum is full of new innovations, bringing in opportunity for project to access into their blockchain and create something new, that's why DeFi projects can be able to come up because they are basically built on ethereum, so however I see no reason why other altcoin can kill down ethereum, ETH remains where it is now.
