Of course demo account is used by many people for trading but for those who are experts and have long trading experience there is no need to use demo account for trading. However, for those who are completely new to trading and have not gained any experience for the time being, if they use a demo account, the risk is less and they can make themselves an expert from the demo account and then discard the demo account now.
To me, the Demo account has many values for many subjects:
1. For new traders, the Demo account helps them apply the knowledge they have learned into practice to experience success and failure, thereby choosing the most suitable trading method for themselves.
2. For experienced traders: the Demo account can be used when he holds long-term and still wants to practice his trading ability. I myself still use the Demo account to test the effectiveness of the new market analysis method in terms of profit and trading psychology management.
Therefore, traders do not necessarily have to give up their Demo account when they are ready and start trading with a real account. I believe that knowledge and experience are never redundant for the trading journey!
