Going down and rising no one can answer when the time will occur because it is very dependent on the market state. What market situation is what I am the level of how high the demand and supply. Very common what is conveyed this. I am not an expert, so don't make this an answer that you can hold.
The most influential impact when prices fall. For me from the positive side is that people can buy a lot and return to be used as long -term assets. From the negative side, maybe those who buy are just buying without knowing what they are bought so they panic quickly.
