I thinked a lot of time at a solution to this problem and the best one I found it's this:
In case the campaign does not reach the objective, I will offer to every contributors the regular license of PragmataPro™ at €20 (instead of €170) also if the contributor donate also just $1 only. At the end of this campaign every contributors can claims this offer. But please don’t offer anonymously if you want this discount.
It's now written in the fundrasing page of Indiegogo and for me it's like to be signed with blood...
