Ask yourself, if you are selling a loss at this time, for what and to whom do you sell?
If you are good at short trade to increase your coin number please. If you do not have that skill, ask yourself, why should I sell a loss?
Are you afraid crypto will end in this February?
I think not, crypto is not pokemon or agate. It's an era, a new era for the internet. We just started, then you stop here?
I think if BTC can survive the bad news of massive hack on MT GOX the previous year. This year's news is just gravel dust passing by.
Bitcoin is the future currency, most investments are done for the case of the future. Investingin in bitcoin same as you invest for the future, whether it's to increase your wealth in the long run by holding it, or whether it is to avoid risk by selling it in panic. If it was me, I would prefer to hold it even bitcoin or others decrease until it price's rise again.
