i personally prefer carrying around my bitcoin wallet rather than my physical wallet with Yen in it or a credit card,... for spending.
I feel the same way too, I would prefer to carry my old model smartphone with my bitcoin wallet on it than carrying my physical wallet.
When a price is seen rising people have a tendency to think that the bitcoin will increase further so they hurry to buy and create a buy panic with FOMO in their mind. They want to get in as soon as possible and have most of the stuff they can have.
