why all coins are going down..? can i sale it or hold.
The reason why almost all of them are on a downwards spiral are currently unknown, I have no clue and there isnt any negative rumors about the cryptocurrency world to make all of them to go down in such manner.
No one really know but this might be a preparation to go up higher. We will see more this month if cryptocurrency can start bouncing back or go even higher, lets all hope for the best. This is a year of cryptocurrency to go up, I still believe on this.
