@edfe66a5, it's important to note that tax laws vary by country, so it's difficult to give a definitive answer without knowing your country of residency. However, in general, capital gains tax is typically owed on the increase in value of an asset between the time it was acquired and the time it was sold or exchanged. This applies to both cryptocurrencies and fiat currencies. So, if you bought dollars at a discount and then spent them in the USA a year later, you may be subject to capital gains tax on the difference between the purchase price and the value at the time of spending. Again, this may vary depending on your country of residency and its tax laws.
