At our meetup, we have the program of "Dash for Dish" were instead giving free drinks-food, we reinburse the value of the expense in DASH. So whatever people get on Starbucks (frappucino, paninis, etc) will show the ticket and get the value of it in DASH.
This makes people get a DASH wallet on their phone, and get to take some DASH back home. Also they get to experience the intense grow of the value. So people are more invested in it.
Please let me know if this can work for your meetup.
