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. 
This is a dilemma for all who have altcoins, especially bitcoin, I think if you sell it you are experiencing a big loss and so am I.
I did nothing but observe and search for all new information concerning the crypto market. and now the most logical thing to do is fast trading.
