Why are you putting on the helmet? Would it not be more visible on a t-shirt or something..? You can put some funny comment on the t-shirt... saying something like :
"If you take photos of this body, you have to pay in Bitcoin"
"Photo tipping to this address ---> {insert Bitcoin address}"
Remember the QR Code are used for many other things too... the Bitcoin symbol should be bigger, if you going to draw attention to it.
Idea of tipping for a photo is good. "If you take photos of this body, you have to pay in Bitcoin"
"Photo tipping to this address ---> {insert Bitcoin address}"
Remember the QR Code are used for many other things too... the Bitcoin symbol should be bigger, if you going to draw attention to it.
But printing qr code on t-shirt isn't, because due to wind, and moving bicycle, the qr code will not be captured properly by camera.
And most importantly, the photos will be captured from side of the road and not from front.
