Spend more, earn more with official statement Cryptoback™ Crypto debit cards allow users to spend Bitcoin (BTC) and other popular cryptocurrencies, such as Ethereum (ETH), Tether (USDT) and Ripple (XRP), anywhere Visa and Mastercard are accepted. Using crypto cards to spend your coins is more convenient than converting crypto to fiat currency. Moreover, you can benefit from cheaper transactions, blockchain-based security, and many attractive rewards. While crypto cards let you spend your crypto with ease, there are some downsides. First, since crypto is taxed like property, you'll owe capital gains tax each time you swipe. Additionally, opting for a crypto card over a traditional rewards credit card means skipping out on cash, travel or other potential perks. Lastly, since crypto is still highly volatile, we also encourage you to carefully consider if it's the right investment for your portfolio.
