Maybe because we have investment in higher amount, so we need to have higher price so that we don't have any loss in our investment. Also, we want higher price because we want higher income.
You're right. Because if the price will go down and you invested in bitcoin when the price is still very high, so you are losing not gaining. But to those people who bought their bitcoin in a lower price, it is nit a problem because they can still earn even if it will keep on going down its price since they bought it in a lower price. They don't have to worry about the price down.
