To me the gradually growing Altcoin is NEO,its called Chinese Ethereum because its also based on updated and modified ETH smart contract technology.I also studied about its development team,very competent and experienced in block chain technology.I think if Ban news in China stop,then this Chinese product NEO can bring revolution in coming years,it may overtake ETH in upcoming few years.This is my extensive research about NEO.Share your ideas.
Even after 2 years since you posted this, NEO is still nowhere closer to Ethereum.
Polkadot is fastly catching up with Ethereum than NEO.
My favorite alt currently is definitely eth and dot. Both have bright future and can make one millionaire.
