I believe that we can develop our hobby in parallel with our main job and quit work only when we have managed to develop our hobby well enough. Bitcoin is a good investment, but it will be meaningless if we do not have the funds to buy Bitcoin.
The same thing to running a business without enough capital to sustain. Because investment doesn't give us instant return we can fully rely on it, maybe months after. That is how important to have a least another source of income to back it up while waiting for our business or investment to grow. We can just quit working on other people if we are really ready and when our investment/business can already support our living. In order to have a good living, we also have to make multiple sources of income which is somewhat hard for poor people and I feel how hard it was.
It is true that no business investment is possible without sufficient capital. Investing in crypto is good but we have to wait for a long time in investing, if there is no source of income then no one can live a normal life. Income is one of the most important aspect of our life money is needed to carry on other activities to meet basic needs overall development. If you have enough money to keep investing in a currency like bitcoin and have a source of income it will be easy to back up as the price of bitcoin increases and you will get good profits.
Ive seen in a lot of documentaries that they are living in the forest so that they can escape the city but still they are needing to sell some products so that they can buy food like rice for their daily needs. In today's generation income is crucial to living no matter how big or small. Without a source of income it is close to impossible to live or if we can we will struggle on a daily basis.
If you are planning an investment and are still short on money to invest in it is better to not push it through because it is not enoug so probably it will fail. As long as you've already accumulated enough money that you can afford to lose and is also enough for an investment that is the time that you'll need to push through as long as you've already gained knowledge on what you are investing in.
