Bitcoin bullish momentum always affect altcoins and I strongly believe that bitcoin is going to get bullish this year. Altcoins has refused to recovered since December 2017 and we hope this year is going to be different because of the halving.
We will need more time for altcoins to recover. But not all altcoins will recover like 2017. most of the current altcoins are dead and there is no volume, if halving bitcoin helps the market grow then I think only the altcoins in the top 100 will increase price. The bitcoin market has completely collapsed and a lot of people are stuck there
Of course, not all altcoins can recover well this year because the current investment demand is still very low and people are still very afraid when investing in this market. I think you should spend a lot of time researching some of the new coins that are available in this market because this very good options for you to make good profits and surely 2020 everything will change a lot about the value.
