you need to research Aethernity, it is good platform project, why i interesting on AE, because i like to invest to Platform or infrastructur ICO, it will give you very good return if you put your money in the right infrastructure project. AE still cheap, why not ARK ? ARK also good, but the price is already 300x from ICO price, i have no doubt ARK will goes to $10 but i want to wit $2 ARK, seriously, if you want to buy altcoin, consider to buy infrastruktur project like ARK,LISK,Stratis,NEO
I hope you know that the main developer behind Aethernity is gone, so if you are betting on it long term, who is going to develop the platform? I know alot of smart contract platform in the space that is going to make AE an obsolete idea
