lots of coins that are hard to get up after the 2018 market decline. trading volume declines have occurred in altcoins and most are now turning to top market coins. be careful if you want to choose assets with low trade, there is a possibility of going back up, but it won't happen quickly.
They are really on the hard recoveries just because it never has such a promising look and investors skip them for their coins of selections. It better to look at those low marketcap coins that already show some good market trend before as it has a huge possibility that it will rise up later and get profitable.
