Gm #lensfrens 🌿, These days, I often see that artists and even big collections are using the open edition mechanism. Why?

Have you forgotten that one of the valuable factors of a work of art is scarcity? When you unlimit supply, you destroy respect for the value of your work. Supply must always be lower than demand; this is a critical law. 
Let a powerful secondary market develop to add to the future value of your works. https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcTc67Kd1u_4GOk4QEvyPyuWAmYyGYEG7rekuw&s
