Based on our country, you cannot actually get away from taxes in cryptocurrency conversion to fiats. How? Because if you have local exchanges, then that is the place where you need to convert your cryptocurrency. In this case, what you need is to pay transaction fees with taxes from conversions. What is good about it is that, if you have huge accumulation of cryptos, instead of converting, you could transact and pay in crypto without taxes.
If we want to actually use crypto in real world for payments in most cases we need to face the problem of conversion. Thus we lose money on exchange rate, taxes, fees and etc. So far the only or maybe the cheapest solution for me is to use crypto debit card. No need to worry if crypto is accepted, no transactions fees and taxes.
