I did a review on Dash recently, its not all good, although most of my criticism came from their dodgy beginnings. I do think Dash is a decent option for what you are trying to do, Decred and PIVX both have treasury systems you could try and I prefer Decred to Dash. I also think Steem could be quite a good option if you can get your hands on the Steem somehow. Maybe start a "help Venezuela" account and people can go and upvote/donate to it and every time you get a full steem you give it to a new person?
