The bad economic conditions in my country have made survival my most important priority. The high cost of living caused by inflation has made survival difficult and saving impossible. Most of my colleagues in my workplace are taking loans to survive because our salary cannot cover our monthly expenses.
However just as you said OP, we have to plan for the future because the time will come when we might not have the strength to work as hard as we did when we were young. Seeking alternative means of making extra income should be an option to enable us to save and invest in viable businesses. Bitcoin is a good investment option and using the DCA strategy is advisable.
I came from a society where majorities are not bothered about their retirement plans, Some do have the financial resources but due because of financial revenue opportunities, they feels so reluctant and comfortable without considering that depending on the government opportunities could get to an end somedays. I don't know if they ever have the picture imaginarily about how their old age times would be.
Anybody who fails to make use of his opportunity at a young age will have to suffer the punishment of wasteful spending. The understanding that there will be a time when you might not have the opportunity you have now to make money triggers the drive to keep saving and investing for the rainy days.
