I didn't expect to make a profit from last month's daily expenses.

Here's the thing - one day I received a cashback notification, indicating that the down jacket I got on Black Friday won a full refund. I was stunned at the time; could such good luck really happen to me?

Recently, I've been using a Web3 payment card that offers 6% cashback on everyday purchases. Coffee, takeout, and online shopping all count, with USDT credited in real-time. Even more outrageous is their lottery mechanism — every day, they randomly select orders for a full refund.

The operation is indeed smooth. Binding the wallet allows encrypted assets to be spent directly as fiat currency, with real-time exchange rates. There's no need for back-and-forth currency conversion, saving a lot on fees.

If cryptocurrency payments can really take off, daily consumption scenarios might become quite interesting. At least the current cashback rate is indeed more appealing than traditional credit cards.
