If there are sides hustle that can add more income, then @JayJuanGee is right. Some people are already working hard beyond the minimum wage, so anyone who crave for a better future should endeavour to explore other areas that can earn them money.
Fortunately, I know a lot of hardworking people from Bangladesh that are doing multiple freelancing jobs to make ends meet. This is not perculiar to Bangladesh, many people from low income countries strive to earn more money to be able to meet their needs.
To invest in Bitcoin and manage the investment effective requires that one have a cashflow that will meet basic needs first then investment funds. If basic needs are not met, there are chances of selling unplanned even in the case of emergency.
Having several sources of income will certainly be very good for us because it will be able to meet our needs and other things. Yes, you are right. Anyone who has the desire for the life they dream of must have several sources of income and it would be even better if they invested in Bitcoin. If indeed they understand it well in making investments, of course we have to use idle funds so that we can buy and hold them to achieve profits from the investments we make.
