Yes you are right, if for example you do not have any income at all the first thing you should think about is not investing, but finding a job first so that you have income. Because if you do not have income how will you have discretionary funds. Even if you do not have a job how will you buy necessities for your life. That is why if you want to invest in bitcoin, but do not have a job, the solution is definitely to find a job first so that you have income. Because basically investing in bitcoin requires discretionary funds, whether it is large or small. Because if you force yourself to invest in bitcoin like using borrowed money, I think that is a bad idea. So my advice is to hone your skills first, then after that apply for a job and if accepted then you can think about investing in bitcoin after all your needs are met.
I think it would have been better to use the word "source of income" instead of using the word "job" here. Whether we work or do business or earn in any other way is not important for investment. Rather, you need to have a source of income for investment and have discretionary funds after meeting the necessary needs.
When looking for a source of income, it is good to have some certainty about the source of income. That is, there should be certainty about the life span of the source of income so that your source of income does not suddenly and unexpectedly stop, stability of income or a clear bottom line of income so that it is easy for you to plan monthly. Even in the context of your country, you can check some other features and look for a source of income. You should keep in mind that the source of income should be one on which you can invest for a long time and even if it goes away, you should be given time to find an alternative source. The source of income should not be such that you have to sell the investment due to the source of income and you face losses.
