For longterm for sure Aion, still at a very low price and has the option to go up 100x. It's an excellent technology and will play an important role in the blockchain ecosystem. NEO is Chinese Ethereum and will for sure get closer to Ethereum level over time.
My favorite is 0x Token (ZRX). They have an amazing platform for trading tokens on Ethereum platform, the app works great and a lot of decentralized exchanges already user their protocol.
Probably it has quite a lot of potential. I'm going to purchase a few BiBox Tokens. If it's going to go the same direction as Binance and Kucoin it's going to be great ROI.
Looking interesting. BiBox exchange is listing more and more coins. I think it's a good investment to purchase the BiBox Token now when it's still low.
