I think that this is a situation that is special to the U.S..
In my country, you are exempt on paying any capital gains tax on crypto transactions up to a certain amount.
I think it's the other way around. Without having made an exhaustive study, in most countries what has been imposed is a capital gains tax. What is an exception is what happens in your country.
In my country, a bill was passed in the first reading according to which cryptocurrency will be used as a means of payment. True, indeed, while I cannot say how taxes will be paid. The bill states that the amount of taxation is determined as the difference between the amount of the sold cryptocurrency and the cost of purchasing it, and it is assumed that the tax amount will be five percent.
But what will need to be done in the case of buying goods or services directly for cryptocurrency, I do not even know. Perhaps it will depend on the value of the product or service.
I don't quite understand. If Bitcoin is used in your country as a means of payment, you shouldn't have to pay taxes for buying a coffee with it. I imagine that if you exchange Bitcoin for local currency will be when you apply the 5%, and we will have to see what happens when you buy a coffee. Ideally in the latter case there would be a minimum exemption, for example $100 or equivalent, below which you would not have to pay anything to buy directly.
