Every person invests for the future so that they can get a good result in the future or earn a good amount of money from it. As you said, investment is never done with the hope of profit. Investment is always done for profit but investment is long term so that we can get a very good result in the future.
If investment is not done aiming on profit what is it done for? What or where you put your money without aiming on profit is not investment but charity organisation.
Investing is not something that requires a job or a monthly salary. No matter what job you do, if you have a source of discretionary income, you can invest. If your income is low, but if you are willing to invest, you can reduce your extra expenses and invest with it. Invest with the amount of money that you do not need. You do not need a monthly income or stable income to invest, just determine whether you have a source of discretionary income. If you have a source of discretionary income and have basic knowledge about Bitcoin, then you can start investing.
What in the name of investment are you presenting?
How can you go long on bitcoin investment with having a job or a stable source of income that can be counted on. It is a failed investment journey that you are planning on bitcoin investment without any form of income. Without the job or a source of income how do you plan on having a discretionary income left?
Let assume you are not in tone with what discretionary income is. It is what is left for the bitcoin Investor in his total income after making all his essential expenses.
