Panic is the biggest mistake of newbies nowdays because they trying to sell everything on first huge dump. At my opinion people who made long term investment should keep mind clear and just wait for a good opportunity.
I can't see why anyone would be selling right now, other than those who are in a state of panic, the price is so low and anyone who understands these things must understand that generally what goes up must go down and vice versa, a recovery will come, it's just a question of when.
