During the last week I bought coins and they almost immediately fell by 10-15%, and today early in the morning I saw how they fell by another 15-20%. How long will it last?., and whether I should sell for what I have. I wouldn't want to be left with empty pockets. 
Yup, this bear market is now on another level. What we are experiencing is the panic sell. Or, at least, this is what I think. Bitcoin and all the other altcoins are literally deep in the oversold zone. This means that people are selling at a loss and they are selling fast. And there is not a logic reason behind this mass selling, too. Bitcoin and the altcoins had a lot of good news during the last 12 months. I really don't know ewhat is happening during this red, red, days!
