Not having an emergency fund was one of the greatest financial mistakes people made last year.
For most people, this is a financial mistake not only for the past year, but for almost all the years of their life.
This is true. But we should also consider the fact like those people are unable to have an emergency fund because they don't earn enough to provide for their daily needs in life.
Regardless of how much or how little your income is, I'll say having an emergency fund is very compulsory, even if you'll have to cut out or cut down a few expenses in order to meet up with your savings or emergency fund.
The same way you don't need to earn so much before you can use the DCA technique to accumulate bitcoin or grow your investment, so is it when it comes to gradually piling up some funds for future emergencies. So yes, even if your earnings are very little, you could still stack up some money for the future .
