To be frank, all of us traders, bounty hunter and investors don't want to be on the losing side. That's why we complain on such things as the Bitcoin is going down again. But there is some good sides here. Like there is a chance of low risk, high rewards profit that will come eventually when the right time comes.
Actually every person is expecting the price to increase, but when the price comes down they become disappointed. it is natural that when something happen against your expectation it make you disappointed and then you will complaint against it, same is the case about bicoin price because investors always have hope from bitcoin price to increase and give them good profit.
You're right. Every person is expecting too much. Specially for those new comers who are unaware or lack of knowledge on how bitcoin works are those people who keeps on complaining things. If they only know how to deal with it they wont complain. Those people also who worry alot and malcontent are difficult to please. Lets not forget that every ups and downs of its price has a big advantage..
