The major factor responsible for the rise and fall in the value of anything is its demand and supply. The same applies to crypto market also. And there are many reasons which affect the demand of a cryptocurrency by its investors. Sometimes whales can also manipulate the market. The type of news about the coin also affect its price. The negative news will make the investors sell their investments and the positive news will make them buy more currency.
