Is it wise to pay for living expenses with your crypto?

Is it in general a wise thing to do, to spend your crypto for example with the Coinbase card to pay off living expenses? I just see it as a way to also use your investments, this could not be done with stocks in the same manner. Both get turned into fiat, but with crypto it feels to work easier, because you don't have to first sell them, and then move the money to a bank account etc.

I feel like I should hold onto my crypto by teeth and nail, because of the potential upswing that they can have. Of course if I am completely out of fiat, then I have to cash out some investments, but when things are okay, I don't see it as a good option. Also, I would feel bad for buying dinner or groceries, later knowing that the crypto I spent could have doubled it's worth. That being said, selling some of your investments to create a better balance in your finances can totally be worthwhile.
