Ethereum will not exist that long!
This coin was a scam from the beginning but with the bailout hardfork to save mostly whale investors and devs for financial desasters, because of investing into DAO, it became totally useless due to loss of immutability.
It's living because traders speculate with it.In a few this coin will have disappeared and it's dev team will probably pull another scam or just relaxing somewhere on the carribean beach and slurping mai-tais.
I do not think so. The Ethereum will survive until at least converting into PoS from PoW. But I am not sure if it will survive after.
If the Ethereum continue to PoW for the next few years, also combine the PoS, then it might be a popular coins for many people.
If it combines the PoW and PoS, it will attract both miners and stakers. But it might have the problem of both PoW and PoS.
