You keep using that word, "can't." I do not think it means what you think it means.

I'm angry that I can't use my money, and you come to theorize that I don't know Oxford English. You should be ashamed of yourself for not thinking further and for not understanding that not everyone speaks English. If you kept quiet, you would remain a philosopher.
I was only trying to point out the difference between "can't" and "not allowed to" using a common Princess Bride meme format. Your English is just fine. You can use Bitcoin without permission from anyone. That's the beauty of it. 🤝
The possible problems and hussles with exchanging to fiat and peer to peer can be real and can come with delay in time...I get the frustration. In some countries it can be a problem I think.
