As a beginner who hasn't mastered something they are new to, it's nice to come up with the idea to test your learning skills from time to time to check whether you will fall into the trap of getting it wrong or right.
Trading is what most traders find it hard not to fall greedy to. I like how you started with a demo account, to check your capabilities in trading, whether you will be carried away by greed or not. Some people don't start with having a demo account on trading; they start to trade like that, making themselves vulnerable to trading with greed. When they lose to trading, they complain to the whole world about having lost huge money on crypto trading, forgetting that they once earned from trading but because of greed, they lose everything.
