We, in steemitcryptoacademy, focus more on practical knowledge than theoretical knowledge and that is why the question of placing a trade is there. When it comes to demo trade, the students don't take it seriously because they are not losing anything which doesn't happen in the real world of trading.

Demo trade is there for your better understanding and real trade is there for applying the strategy in real life with the real trading conditions.

And you only have to place a trade of $10 which consists of a very small price of your post payout, hope it clarifies the doubt.

Thank you!
