using a demo account is for our learning, we learn from a demo account, learning in a demo account because the demo account has no risk in it when we trade there we can be safe and then if we try to learn in a real account there are lots of risks, learn strategies in a demo account and study psychology in a real account and in my opinion there is no difference between a demo account and real trading about trading but the difference is real trading with your own money and get profit or loss but demo is only for training purposes
