It is really hard to say most cryptos are a good investment right now. Honestly ETH and BTC are going to continue to grow in price. ETH due to phase 3 will be completed in the next month to 90 days from now. Huge price rise due to that.

BTC will solve it's problems and everyone will just pour into it even more.

Some other alts like Steem and Ripple should continue to do well.
