For now, I simply trade them on an exchange an convert it to fiat. But trust me, maybe in 10 years time, they'll be more use case for bitcoin. BTW, there are online stores that actually accept bitcoin as a means of payment (
see here). So you don't really have to make use of it in a physical store. However, it's only a matter of time.
Why do you post outdated stuff?
These are posts from 2017, at that time way more merchants accepted bitcoin than now.
Steam and Microsoft stopped accepting it for years. The same with subway and DISH.
This times are over. Fees are 14-20 USD. BTC is not bitcoin anymore, due to many reasons.
