There are so many altcoins with lot of features and different type of usage, some of them are fake and some of are very good.
What coin do you think technically the best among them? (Don't just judge by the popularity or by the market price. )
I won't be original and say it's Ethereum. Because it is a platform, because the project is managed by a great team and it is constantly evolving. I think that Ethereum can become the basis for many financial systems and economies of the world.
