What to do if the prices down again, First is consider the previous trend, like knowing when it will drop and when it will rise, because of that, you were prepared what to do in case the price comes down again. If the price comes down again, you might still hold it since you are hoping that it will rise again in a given time. You might buy many coins since the price were very affordable, or you might sold it since the price continues drops and less possibility that it will rise.
If the prices drop again and which will absolutely happen many times in the future, the investors should keep this in mind that digital assets recover also. Digital market is an unstable market so such fluctuations are normal. Instead of getting frightened by such changes, on must try to get benefit from these. Besides, it is not possible to buy a coin at cheap rates without having declines.
