No no I don't buy anything goods or services using cryptocurrency online virtual currency because my country don't directly permit bitcoin as trading system.
Lots of people still use Bitcoin to buy Goods and Services even if their countries don't permit to use of Bitcoin. the thing is even if govt don't allow that, it is technically impossible to stop anyone from using Bitcoin in online sources.
yes, you can't use that in real life. but there are still countless ways of spending Bitcoin online. you can even buy physical products with Bitcoin. like Mobile phones, laptops, hardware wallets, collectibles, and much more.
and no one will ask you how you paid for them. unless it's a noticeable thing.
It is true what you say, most countries prohibit or impose restrictions on the use of Bitcoin, because it creates legal problems for users. However, the fact is that many transactions use Bitcoin, even though it is against the law, they don't care about it. Please note that everyone who takes risks in their work must have thought about it at the beginning.
