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. 
No one will be left behind if we will only remain patient,since we all know that theres no permanent in this market,even the growth of the falling,whats only in permanent position here is the volatility everything changes in price constantly,sometimes earning but now more on dropping so if you wanted to gain better stop frustrating yourself and just wait calmly and trust the market capabilities
