What would it be like to wear a Bitcoin QR code t-shirt?

     How vulnerable is the Bitcoin physical theft prevention system? I'm sure many people have this question, because it's hard to imagine someone stealing a non-real currency. But if your account information is displayed on your body, then there is still a certain possibility that Bitcoin will be stolen. Recently, Tal Newhart, a business strategy and recruitment expert from Chicago, conducted an interesting social experiment.

     Tal Newhart and his assistant wore two T-shirts with QR codes printed on them . One T-shirt read: "Bitcoin Research, Please Donate. Don't Ask Me Why." Then they wandered around downtown and suburban Chicago for a few days wearing the T-shirt , which subsequently brought them $65 in donations.

     Another T-shirt was printed with a new QR code and marked "SHA-256" . The term SHA-256 refers to the encryption algorithm of the Bitcoin account. People familiar with digital virtual currency can scan the QR code on the T-shirt with their mobile phones to obtain the funds in their accounts. Then Tal Newhart wore this T-shirt to eat lunch in downtown Chicago. However, less than 5 minutes after the lunch started , he received a text message notification that $68 had been deducted from his account.

Tal Newhart believes that the generosity of people in the first experiment shows that everyone is quite supportive of the development of Bitcoin. The second experiment shows that people can also be thieves, and they are lurking around you. After the experiment, Tal Newhart joked: "Not all Bitcoin thieves are Russian nerds, they may also be hypocrites wearing Armani haute couture."
