The answer to this question depends on the individual trader and their level of experience. For those who are just starting out, it is often recommended to practice trading on a demo account to get comfortable with the process and to develop a strategy before risking real money. For experienced traders, demo trading may not be as important, as they are more familiar with the markets and have a better understanding of how to manage risk. However, demo trading still provides the opportunity to test out new strategies, or to practice trading with different types of financial instruments. Ultimately, the answer to whether or not demo trading is enough will depend on the individual trader's needs and level of experience.
