As you can see the area i highlighted that is where you got it wrong, how can you say that having a steady source of income doesn't guarantee that an investment will last long, are you for real? If an investor do not have a steady flow of income how can he be able to continue making accumulations and build a solid portfolio in the long term?, In fact, i put it to you that having a steady source of income is one of the prerequisites that guarantees long term investment.
You feel very much guaranteed with long-term investments. Having a fixed income source is one of the basic conditions for starting an investment. So just because you have a fixed income source does not mean that you will be successful in long-term investments. Not having a source of income means that it is risky for a person to enter the investment and that you are not a suitable person for investment. But if you consider the source of income as the only element of success in investment and think that having a fixed income source will make you a sure long-term successful investor, then you are in a hurry. You may be forgetting about long-term protection or avoiding investment risk management.
Having a fixed income source means that you have unnecessary money, sufficient cash funds and the ability to create backup funds. This does not mean that you have all the knowledge, the ability to take the right steps at the right time, the patience to achieve long-term goals or the determination to succeed. There is nothing in investing that can definitely make you a successful investor.
A steady source of income may qualify you for investment or may make you see an easy solution or easy path to take any action. But it cannot guarantee you success in long-term investment. No matter how skilled and knowledgeable an investor you are, none of us have control over Bitcoin. So you should always be prepared to lose the money you invest and leave your holding portfolio to fate. Although the chances of success here are high, it is not guaranteed.
