I agree with you. it needs extensive knowledge to join in the world of cryptocurrency. if we are wrong step or too hastily in making a decision then we will fail and get loss. experience is also very useful to help us in order to be better in the future. it's never too late to learn and increase the knowledge.
I think practical experience is the most invaluable knowledge. Even if you lose money, you will gain experience that you will not give any theoretical knowledge and the loss can be considered a fee for studying.
