I’ll give you a €10 gift-card to whatever popular online store you want. I ask for nothing in return. Absolutely no stipulations. The only thing is that you have to give me your credit card number and the expiration and the numbers on the back. I’ll just verify it’s real with a €1 charge (and then return the €1). That’s it. Not gonna do anything with the data. In fact, I’ll delete the data afterwards. Want €10?
You know China can just buy your data, right? It’s easier than entering a monopoly and beating the dominant player.
