A better idea is for users to buy Gulden to increase the price and let the dev funding pay for the exchange. Is the 50k what bitvavo wants or wishful thinking? The devs can take the Euros back if the submission fails instead of users contributing and never getting the funds back if it does not succeed.

Alternatively sell Gulden at 2 or 3 times the price from the dev funding , at least the funders receive something in return.
