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.
Then the waves can also be viewed as a perspective. While neo does not have support from China, it will be heavily tossed at a price. And of course now the coins are a variety, but for me the best and not promising is still Dash.
