Which are the best competitors to Ethereum, and why do you think so?
(I know on top of my head that Cardano and IOTA try to challenge Ethereum,
although they still haven't proved much from my understanding?)
If I believe in the NEO, one day it will rise and its popularity will be able to compete with the platform of ethereum. But it will take a long time for the next three or four years to be able to prove the NEO.
