Reduced Tax Burden

Kardex offers a smarter alternative to traditional crypto-to-fiat conversion methods, which can trigger significant capital gains taxes. With Kardex, there are no transaction fees or annual fees for using your debit card. The 3% fee applies only to $KARDEX token buy/sell transactions, which is then redistributed to $KARDEX token holders, potentially reducing your overall tax burden compared to direct crypto sales.
