This list of coins is in my opinion are the most sustainable and realistic in the crypto space.
1.) NEO
Neo is the Chinese Ethereum and is a little better than Ethereum because programmers are able to understand the language that it is built on unlike Ethereum.
2.) Walton
Their are a few supply chain tokens out but I see Walton chain being the one that out lives the rest, reason being they have since 2013 to figure out the game and develop a product.
3.) EOS
Another platform also similar to ethereum but faster and more advanced, bet i mean hey EOS does mean Ethereum on steroids
4.) Icon
Ethereum like platform but based out of korea, as we all know Korea has a big affect on the market. I really like the project and with a price of around $8.00 (during stable market) you could make series gains!
5.) Steam
Steam is one of the best investments you can make right now as of right now its the Facebook of block chain and even on the down days, it hardly moves! I can see steem being around $40 by the end of the year!
