Trading is also not a job, it is part of the investment field. Have you ever seen someone who can make a steady income from trading? Has anyone ever considered trading as their main job and relied on it to survive and be successful? I guess not many people can do that. Honestly, I have not seen anyone who can survive by investing in bitcoin and relying solely on it for survival. Whether he is investing or trading or even a combination of both.
Also, I disagree when you say that poor countries can earn income from trading, is trading easy to make money?
Their are people who do trading full time even if they don't get money in every trade they still decide to continue and also show a lot of dedication to what they are doing, because no matter what the process of earning might be dedication matters a lot, and even the little you are getting from it will be appreciated and that is why we need to pay a lot of attention especially when we are trading. And if it's about steady income from trading their people that they don't do any other thing than trading and they are doing very well. How you manage what you do matters a lot, and the reason why does who really fully in trading are not many is because a lot of people are running from the kind of responsibility that trading comes with but if you ensure to show dedication you will find it interesting and you will do everything possible to make money from trading. A country been poor does not have anything to do with trading, it's a choice if they want to trade or not and capital is another thing, they might have interest to trade but no capital.
