You have a point, but I don't agree with the idea of having a fixed deposit account for an emergency fund, especially since it is seamless to exchange Bitcoin for fiat.
First, if you're going to use a few BTC for an emergency fund, and the market downtrend, it will only lose a few dollars, or cents, sometimes, if calculated in fiat.
I don't think it will be few dollars but may be few hundred dollars. It depends on how much you hold for an emergency fund.
While everyone has their own budget, it should at least cover 3 to 6 months of your expenses.
So even if you hold, lets say around $2000 in bitcoin and if the price drops 10% then you would still lose $200.
Second, there are many crypto cards, each of which we can deposit Bitcoin and have it in fiat currency, which technically secures the volatility aspect of the market. Besides, we can also convert the BTC set for emergency in stablecoin, either, and this is what I always do to use crypto for the payment for goods and services.
Oh yeah, stable coins are a good option. That would solve the problem
