The biggest difference lies in your own mentality. When you do simulation, you don't care about winning or losing, but you make a firm offer and make money. You are afraid of losing money again, so most people just make a little money and run away. If you lose money, you always expect the price to be adjusted back, and you can't bear to cut meat. In this way, you are likely to lose more and more. But the simulation will not have the heart to cut the meat. This is the biggest difference. So some people think it is useless to do simulation, because the success of trading depends largely on your mentality.

But, think about it, if you can pay fake money first, don't you have to pay real money?
