IMO if you want a safe, diversified crypto portfolio that will bring good long-and-short-term returns:
20% ETH
20% BTC
10% LTC
10% WTC
10% NEO
10% XRB
10% XLM
5% COSS
5% IOTA
Assuming a $1000 buy in I wouldn't be surprised to see you double your investment by 2019, with the potential for a LOT more gain. But remember: don't invest what you can't afford to lose. Ultimately it's your decision.
Thank you so very much. I am not very expedience in investing and love all the help/advice I can get my grubby fingers on.
Good luck! :)
