This seems like a good time to make an investment. Buying now will surely profit good in long or short run, because the growth can get initiated anytime soon for a long term stable growth. Find the coins with good circulation volume and has reached peak in the past and invest upon the same.
most of coins already reached the peak level at the past.and now their price in dippest level.just pick one them that has good feature and team developers will make our investment could be worthed in near future.dont forget to pick coins that have large daily volume trading.
but I don't think just choosing one coin to invest. but it would be better if we choose some potential coins, so that it will reduce the risk. besides that we must remain faithful and be patient waiting for the bullrun to come
