Even today the best options are still the big coins. Those big guns are here to stay and they will not go away anytime soon so we will have to check them out at first. No other investment options are not returning back as how crypto currencies are doing. If you calculate from bitcoins down in the beginning of 2015 to ending of 2017, I am sure no other options will match that ROI.

Coins like bitcoin, ethereum, litecoin, dash, ripple and coins that big, if you invest in stuff like that you may have some big swings because they do get affected a lot and prices drop or goes up really quickly and swings are high however they are the ones that will eventually go up as well, price will recover for these coins and they will increase in the long term investors so if you really want to invest in something, invest on the top coins.
