Hold, sell and buy must be based on an analysis.Especially as to sell at such low price as now nobody wants.
I agree that people should not take decisions as important as those based on their feelings, people need to have a reason of why they are doing what they are doing if they are not then they have no strategy in place which means that most likely they will fail when they are faced to make those decisions, in the other hand the one that knows why he is buying or selling his coins and when he wishes to enter or get out of the market has bigger chances of success just because of his systematic thinking.
So to all of those people out there thinking about doing something remember the next, first try to determine what it is the best course of action and once you do that then you can do what your analysis tells you.
