Here in Philippines, we have some digital wallet such as coins.ph, gcash, and paymaya. Theres a lot of advantage if you have digital money. But of course, you cant buy goods if you dont have cash. There are more products and services that use cash than digital currency.
I think your money will always be safe in a digital wallet so you can go out, buy goods and even pay for transportation without the amount of cash in your wallet, also faster to transact using digital money than fiat.
When everyone will use digital money in the future, it will be very different from what we have now, there will be less crime
