It is also because of the number of its supply and demand that makes its price high or low. Supply and demand for me is always opposite at each other, when there is an increase in supply there would be decrease in demand and if theres is a decrease in supply there would be an increase in demand. Take for example in the normal market wherin it is time for holidays like Christmas and the demand for good and services are high so it would mean that the supply would definitely decrease and the price would be high or would pump drastically.
