Don't have any savings, only BTC

With the recent dip I bought btc with everything I got (after I sold it a few days ago I bought back), now I'm at 0.xx BTC. But I even used my emergency fund for it, I literally only have 1k Euros on my bank account for my rent and food, and I'm worried that I have no real savings, it feels pretty risky to have only BTC and nothing else. It doesn't feel like reliable money right now because the price can dump any day without warning, so I guess I should start saving up a new emergency fund using only my income in the nexrt months (not by selling BTC) instead of taking further advantage of the current bear market low prices. How do you guys handle having only BTC and no stocks, fiat?
I would really like to buy more BTC when it falls more, but I also want to save up an emergency fund. Its really not a good feeling when you have to choose
