Recently, more and more cards are being released that allow you to earn cryptocurrency every time you shop with a credit card. Instead of points, you can directly accumulate Bitcoin or other cryptocurrencies. It's interesting because you can start investing in digital assets with zero initial investment.

After doing some research, it seems there are about four types of cards available domestically. From standard cards with no annual fee and 0.5% cashback, to high-end cards with cashback rates over 1.6%, there are quite a few options. The assets you earn are not limited to Bitcoin; some cards allow you to choose stablecoins, so you can select based on your risk tolerance.

Personally, what interests me is the feeling of steadily accumulating through daily shopping. Unlike points, the cryptocurrencies you earn have actual asset value and could appreciate in the future. However, tax reporting may be required, so it's best to check that in advance.

For beginners, a no-annual-fee card is recommended. If you prioritize cashback rate, go for the 1.6% option. If you're worried about price fluctuations, a card that offers stablecoins with fixed value might be the best choice. Choosing according to your lifestyle and gradually building your crypto assets through everyday transactions doesn’t sound like a bad idea.
