This indeed are great indications of bitcoin mainstream adoption/usage.
We could expect a lot more adaptation that is going to happen in the cryptocurrency, But I might just do this if bitcoin or other cryptocurrency is already popular in my country.
I'm planning to invest in some apartments so that I could earn a passive income and I think cryptocurrency as a payment option is a good thing and at the same time I'm investing in their payment.
The only problem is some people here in my country are still not aware of online things or bitcoin, a big percentage are still more into fiat money I guess because people don't trust online money yet here.
