I order food delivery at least once a week now. That's 100% in Bitcoin. When possible, online shopping I try for Bitcoin options. They actually end up being the same cost or sometimes cheaper. Amazon with Purse gives you at least 5%, for example. If I could pay for movies and popcorn with Bitcoin, I sure as hell would!
And why not? We all already know we have expenditures. We're spending it anyway. I earn in crypto, and I still need to convert it to fiat for expenditures. I wish I didn't need to.
Am I wasting my money? That's what Bitcoin is, isn't it? Money?
Yes, you are wasting your bitcoins because you are losing some value today by spending them on useless things. It would be better to save them and spend little of them for as much as possible.
Bitcoin is not like any fiat money that is devalued by inflation.
