Actually two levels of people are more interested in trading as first when a crypto user comes to know about crypto then he loses money while trading. On the other hand the middle class users refrain from trading because they have already lost a lot of money while trading. Moreover, those who are more experienced in trading easily get profit from here due to which they value trading more than investment.
Those that have experienced losing in trading, don't want to try again and choose to hold. While someone who's very eager and optimistic and doesn't let themselves down due to failure keeps going on. It is okay to stop and learn another way of staying on this market.
IF trading doesn't work for you and you think of yourself as a failure, stop it from there and learn another technique to invest on the market as there's no other way than majority's common known.
You have good points, after all, you've said it all to motivate traders, but at times, it's beyond this and it could be nice if some traders just give up instead of wasting money. If it's about motivation and encouragement, I've done that so many times with so many people in years, but at a point, I realised that I was the wicked one motivating people and keeping them losing their money. That's how I realised that trading is not meant for everybody, and no matter how most people try, the more they fail in it. This is not to discourage anyone but to be frank and real due to my vast experience with it and my relationship with different people.
It's worth saying that it is not even the lack of learning that makes people fail, you have said it all that one should learn and change style when one fails, but it is beyond that. You may be well-equipped for trading and still fail, but you may also use the best management and still fail, which makes me know that psychology plays a huge role in the success of a trader. But unfortunately, traders do not always get this right, they might get it right for a little while, but before they know it, they are getting it wrong again, so they will continue to lose in this regard. It is until they get the psychological part of it right, they will learn and learn but will continue to fail.
