If there is a country where cryptocurrency is legal how much is the tax that we have to pay to the government? Also, how can the government track our transactions?
If it is already legally recognized in a country, it will be ensured that regulations will be made regarding crypto, so that the state can take tax legally because it is regulated by laws. if the regulation has been established, it will still be easy to collect taxes from crypto transactions. for example when exchanging with fiat and transferred through bank accounts, it can be directly taxed.
For now I myself have not heard from the country that asks taxes on bitcoin users. only a few exchanges require tax fees on every withdrawal a user makes to their bank account. if the tax is applied maybe about 10% of your annual income to crypto. as the government does for your salary in real jobs.
