There are football players wearing clothes with bitcoin logo and QR code, which represents the address of bitcoin wallet. Scan these QR codes, and others can donate money to the wallet. This two-dimensional code has successfully gained a lot of attention in dithering, and quickly spread throughout the bitcoin community.
So basically he as asking for donation during a football match and i want to know the reason for raising the funds, is he asking for donation for promoting bitcoin or anything else as it is not clear why he was having a QR code in his shirt and if there is a clear answer for that then i would like to know about it.
Next doubt is that how he was able to wear the T shirt and did the team allowed him to do or are they advertising any company.
