I agree with previous posts, ETH has a great potential and great things are expected from it in 2019. I have high hopes about Ripple as well, this coin offers something completely different than the rest of the coins and its potential is yet to be reached. Ripple is popular among investors holders and serious traders as well. I like a new project that I am currently supporting, BTCN. This coin already reached CMC and is present in several credible exchanges. It already has large, supportive and active community and it seems to have a bright future.
