We always say that bitcoin is an alternative currency, yet we don't use it as an alternative, maybe for some they do but most of us? hell no. We are afraid of the volatility, that's the truth.
this is the important point. bitcoin can be used as an alternative payment. But, it is not effective enough for some people. For one thing, because of its high volume, the price tends to change, making it less appropriate to use as a tool for determining value. Bitcoin is more effectively used as an investment tool and commodity trading, its volatility is used to get profit. This all depends on the point of view of each, can not be forced, as needed.
As a payment tool? Bitcoin? Nah. I would rather use bitcoin as an asset for my investment instead of using it as a payment tool for transactions. I will use fiat that cryptocurrency because I don't want to waste my bitcoin. What's the point of you storing bitcoin if you will just spend it as an alternative for fiat currency? You should consider volatility before you make some decisions towards cryptocurrency. You can use ETH, DEX, and other altcoins for your transactions but not Bitcoin.
