Dear @juanmolina
Thank you for your kind and AWESOME reply.
This gives us an invaluable freedom to make our decisions. But will it always be like this? or only during this stage of "experiment"?
Right now this friend of mine decided to support project with 300$. I added little bit from my own money. And I allocated our budget for this project for 2 months at the moment.
Yours
Piotr
