I notice that when there the price is going up so many people are joining the train and they also buy because the price is going up and they are going to make a profit, why people are not buying when it is down when the price will eventually go up and they can make a lot of profit.
When the price goes up, people will tend to buy because there is interest from other investors, while when the price goes down they prefer to sell maybe because of panic. Panic in my opinion is dangerous, both panic buying and panic selling, because we make transactions based on emotions
