There is a quite interesting event - a certain Web3 bank card project has organized a Christmas season benefit, and the gameplay is simple and straightforward.

Before December 15th, by using their crypto debit card for daily expenses, whether it's that morning Americano, lunch takeout, or a taxi ride, they can participate in the lottery by taking a screenshot of the payment receipt and posting it on social media.

The key point is here: the official draws one person every day and directly refunds the full amount of their spending for that day. It's equivalent to getting all your expenses for that day for free.

This marketing approach is quite in line with the style of Web3 projects, using real cash subsidies to attract new users and activate existing ones. For early adopters of crypto payments, if luck is on their side, they can indeed save a significant amount. However, whether one can win depends on luck, as there is only one spot available globally each day.
