In the context of economics, supply refers to the amount of a good or service that producers are willing to sell at various prices, while demand refers to the amount that consumers are willing to buy at those prices. Prices tend to rise when demand exceeds supply and fall when supply exceeds demand. This relationship is crucial in determining the equilibrium price, where the quantity supplied equals the quantity demanded. In financial markets, such as crypto, the concepts of supply and demand can significantly influence price fluctuations and market dynamics.
