Not sure I understand your question. You mean max number of collected business-cards? I doubt we would get more than 500, so total expenses to be funded would be 500x20 + 3x1000, so under 25K NXT.

I also think 50% of them would not the collect these funds, so we can retrive them back, so a deadline is needed.

If this gets 250 people who try out NXT, it's mission accomplished.


I just got another idea - what about using NXT system for activities like geo-caching. Give clues and people search for accounts... accounts contain pizes. Maybe too wild
