If you want to get more profit, it would be nice if you hold it, because the price of coins now again dropped dramatically. If you want to sell it, just wait until the price starts to stabilize again. But from the previous year coin prices had experienced a drastic decline. But I'm sure it's only temporary, in the future bitcoin prices will soar, and people are holding it now and selling it when bitcoin prices stabilize back, I'm sure they will experience success.
Yes, I agree, now is the best time to keep all that you have. After selling a particularly profit you do not get. On the other hand, if you do not have to live on what that part is better to bring.
