Indeed; bitcoin and ripple going downturn but look at other coins like ethereum; Cardano; and neo. They do have a potential in the upcoming year also. This is the nature of this market; as it will rise also it will be down too.
Regardless of whether Bitcoin or Ripple go down or not other coins will also rise and enter the competition its only a matter of time to see which ones will follow.
True. New coins which are also competitive and has an advantage over other existing coins are entering in the market and no one can stop it from happening. But if you think about it, this could also be a reason for the market value going down. Because the market will be crowded of different coins to choose at.
