For investment or to increase the amount of investment, I will focus more on increasing the source of income. If you have to invest in yourself to increase your income, then it will be a good thing to do. Investing in yourself to upgrade yourself may be the right step rather than investing in Bitcoin with scarcity. This will increase your chances of increasing your income and provide additional funds for Bitcoin investments.
It is true that to increase the amount of investment, attention should be paid to increasing the source of income, but it may not be easy for everyone to increase the source of income. I think those who have enough opportunities to invest, that is, those who have enough money to invest. Maybe increasing income sources isn't very important to those new investors at first. The most important and most useful aspect for new investors is to create a backup fund. If the source of income does not increase, then the amount of money you have, i.e. we should invest regularly through the sources of income we have.
