While I don’t wish anyone to make any losses, the truth is that most people tend to learn the hard way. If someone is a beginner and is too confident or even full of themselves that they don’t know you can never learn enough, it is only a matter of time before they become humble. Losing money makes people to slow down and follow a safer route. So yea, most people may have to learn it the hard way.
Sometimes the difficult method must also be considered easy so that a beginner feels enthusiastic about learning because sometimes some beginners will often feel bored when they think it is difficult to learn something that they basically need. Difficult things can always be solved by everyone's high will, so there is no need to think of them as difficult because it is part of the learning process for all beginners who want to make a profit through trading. Although they also have to understand that the risk of loss is not always far from those who are already lucky.
I have a contrary opinion to yours bro, it is better to fake it for me as though it was difficult but to find it easy eventually by myself than for you to tell me it's easy only to later discover it to be difficult. Mental preparedness is what you are not considering here but it goes a long way. It is one of the main reasons people give up on trading easily when they find it tougher than they expected. The easy way they picture it is even better these days when people can easily use Google to verify every claim, this is unlike my days of learning (2 decades ago), it was worse to the point that they would convince you that it's like going to the ATM machine with free access ATM cards. But the reality is always different.
Although the theoretical aspect is not difficult at all, and within a week or two of serious learning, a serious person could know virtually all that is needed to know. But the issue is in practicality, you must be wise and smart, and also be mentally and financially ready. But sadly, it's a very few who can qualify for that even if they learn from today till eternity. This means that trading needs more than mere learning, it needs you on how you can completely engage it systematically and dynamically. But most people are not just patient or prepared for that.
