This is no longer new. The anonymous painter aka p-boy is painting the streets with his art in paris and is painting his bitcoin qr code for his wallet address allowing donations from bitcoin users. I was following how much did he made for doing such things and in the beginning he received 85$ worth of btc then later on it became 1000$ and the latest info was he have already earned 12500$ more or less worth of btc. Possibly sooner or later many artist will also follow his style since even beggars today are using qr code in begging at streets.
Its indeed amazing, well not surprised because the painter express itself through making beautiful art to earn. People nowadays should look at this because some of them scam to deceive or fool the some of us just to earn and get the benefits they wanted without even working hard, there are different ways like using your talent like this.
