My top 5 alts for 2018, expect lots of growth (not including BTC, ETH)
NEO: top blockchain project from China with more than 100 ICOs launching this year, will only get bigger.
NANO: you gotta use it to believe it. Makes Litecoin look like a turtle, and no transaction fees. IOS and android wallets, plus you can use Nano on Twitch live game streaming video platform.
WANCHAIN (coming to exchanges): will be a good competitor among NEO & ETH. Will also launch ICOs on its platform.
ICON/ICX: top, huge blockchain project from Korea, with a very big team and smartest people in Korea working on it, with a mission to hypperconnect the world.
OMISEGO: THE top project on the Ethereum blockchain. Vitalik said when he's done with Ethereum, he will be with the OmiseGo team full time, he really believes in their mission to bank the unbanked. Recently got a partnership with the government of Thailand.
EOS could be on this list, I just hate the fact that they're grabbing $1 billion for their never ending ICO.
Neo and Omise look like good projects, but I am not so sure about others. Nano exploded already and I agree that what they say looks great, but how can we be sure it really works this way and and coin is secure? If there's no difficulty in creating a transaction then maybe it is also very easy to hack? I am even less sure about wanchain. The team is nice and educated, but I am not sure the project can really compete with current giants.
As for icon - I am not against South Koreans, but their government is terrible and made the market suffer for a couple of time already. The coins might be great but end up being banned or something, so I would say it is a risky investment because of this.
