I was just a student back then, putting everything in, and it didn't really matter since I was earning. Because of the volatility through the years of cycles, I learned the hard way, losing a lot because when there was an emergency, or I needed money, I would easily sell my Bitcoin because I needed the money, and I didn't really have bank savings yet for any spending; all my money was just in my custodial wallet back in the day. I fixed my finances and put in a safety net. I realized the importance of having a safety net, investing in the right order, having emergency funds, having health funds, etc.
With that, inflation is just going out of hand; our local currency Dollars is already at 62pesos, increasing its value exchange through out the years, now im already thinking of putting everything on Bitcoin because it is just the same thing, I would lose money because of inflation, I mean in Bitcoin you would probably lose as well, but at the same time you might get profit long term, Emergency fund was not really something that you are going to use everytime, In my experience It wouldn't really going to get touch for months or year, similar to just saving long term, so maybe it is just better to be put on Bitcoin since it was a long term savings as well.
Using Bitcoin as an emergency fund is a great strategy. I have done this myself when I was in a position to do so, and I really benefited from how easy it was to sell my Bitcoin whenever I needed the cash.
As we know, Bitcoin can serve as a form of savings, whether for the long term or specifically for emergencies. If you ever find yourself forced to sell your holdings, you won't face any hassle doing so, given the high demand for Bitcoin. Furthermore, the appreciation in Bitcoin's price can significantly boost the value of your savings. So, I think there is no harm in using Bitcoin for emergency funds, especially if the assets can be held for the long term (which offers the potential for profit).
By the way, I have also thought about how people in the past treated Bitcoin as a sort of emergency fund, sometimes even nearly forgetting about it; but then, when the price skyrocketed, it effectively turned into an investment for them. So, wouldn't you agree that Bitcoin can be incredibly helpful for meeting various financial needs ? (even turning an emergency fund into a fund that helps unexpectedly)
