For daily use, of course, I'll choose fiat. Even though cryptocurrencies like Bitcoin can be transacted in small amounts using satoshi, what if only a small percentage of people accept it as payment? Forget Bitcoin, even digital wallets are still limited in my country; most people still prefer cash. As for investment, I won't use fiat; I choose to save it only for an emergency fund, no more.

For saving my wealth from inflation, I'll prefer gold because my goal is just to preserve my purchasing power, not to gain additional profit. And for getting a potentially high profit, I'll choose Bitcoin because you already know that cryptocurrency can give very high profits, especially memecoins, but the risk is quite high too. So, in my opinion, I'll choose all three, and I can't choose an all-in-one solution.
