It’s not like a research, and it’s just like a kidding. I’m also suspicious that the person who conducts this ‘kind of experiment’ is a discriminator. Because of the difference in cultures, every country adopts different ways in connecting with each other. It’s not appropriate to use email as the only media between each others. The method used in your ‘experiment’ is not fair. Also, the design of your ‘wallet’ is ridiculous. If you didn’t explain it to me, I believe that no one will recognize it as a wallet.
