In my country, the Philippines, crypto owners are urged to declare their crypto capital gains for annual tax filing. This means that we are urged to pay taxes, and I don't think this is reasonable enough since crypto was not yet considered a legal tender.
I'm not sure if this is also happening in your country. Is anyone honest enough to declare his/her crypto assets? For me, taxes should be considered ONLY if it is officially accepted and become legal tender.
There are only two countries globally that have accepted Bitcoin as Legal Tender. Other nations don't make Bitcoin Legal Tender yet but Bitcoin is legally accepted in their countries.
