it's not fair. If someone wants to take profit, then they can just list their bitcoins for sale and earn more money than just dumping them. The only reason people are doing this is to cause panic and grab as much cheaper bitcoins as they can. But people have to grow up.

You know hundreds years ago Mayans was chopping people heads off and they also was thinking that its OK. Now we see it somehow differently. When people will grow up, they will understand that speculating is also wrong because there are winners and losers. Volatile price scares most investors off from bitcoin. If people would not speculate that much everyone would earn more, and everyone who invested would be more happy and calm and could focus on more constructive things to do than watching price for 24h/day.
 Only by cooperating we can have all people winning and this humanity should understand and start consider as normal behaviour. The sooner the better for all.
