Why one euro?
The experiment is not about what one euro buys. It is about the scale of a shared choice—the same small action, repeated across borders.
The global goal
The purpose is to observe how far a simple, voluntary idea can travel. There is no promised destination, only an open experiment shaped by each person who chooses to take part.
Clarity matters
Joining is always your choice. Share only if the idea genuinely interests you.
This is an independent social experiment. Your euro is not a charitable donation.
No profit, return, reward, prize, ownership, or guaranteed outcome is offered.
A participant counter is prepared for transparent public progress as the experiment develops.
