As for me i will suggest ethereum orethereum classic....in few months ethereum is going be stronger than this.both have the tendency to boom.
Every coin is going to have trade-offs. If its value is relatively well recognized, like BTC, then it's going to have less upside potential
but although investment in Etherium is a good option but here you need to invest for long term, as from short term investment you cannot get a good profit, to me think you need to select a cheap coin but having good potential to invest your assets there for short term, and from there you can really expect a good profit.
