but NEO is not the only one that maybe can replace Ethereum in popularidade, like this: Waves, EOS, Qtum, Stratis, may match the demand, though i believe nothing will beat Ethereum.
I think that with time the third will be EOS in many respects, if the team does everything that it promises, then this coin certainly will be very high!
There are 3 candidates that I think would be great for long term investments after ethereum.
2. NEO
3. Daneel
