I think all have experienced losses in the year 2017 and myself have experienced losing money. And this is a valuable experience for me. And for the moment I prefer to make investments for the short term. With the short-term investment, I can enjoy the benefits every day.
I think that long-term investments are also beneficial, just here it is necessary to make a decision not for a couple of hours or days. You are going to hold a long time and spend the appropriate amount of time. Choose a token and track it and see its bottom.
