Need answers from people who are experienced with the stock market

Essentially my friend thinks that the amount of investors in a currency, results in the amount of demand for the currency. Is this true because would that mean that everyone could invest and the currency would inflate relative to the amount of investors? So basically im asking if the amount of investors in a currency equals the amount of demand
