For me it is very difficult to predict a good coin in 2019. Because the market is not yet fully recovered. However, many people think that ETH will be stable and have the opportunity to return to high prices. We'll see next month. Does this really happen or otherwise. To be sure we all hope that next month the market will be better than now.
But hope alone is not enough, because the market today is ruled by panic and the interest of institutional investors, who today are trying to lower prices even lower, as they want to invest even more money today.
