Monica Tobar and Ronald Picso talk about their experience working with cryptocurrency instead of cash to support refugees and host communities in Ecuador. Some key lessons? Just do it--don't spend all of your time trying to get everything perfect. Get lots of feedback--participants will tell you what's not working. Build more supply--get many vendors up to speed on crypto so people have choices about where to shop. Plan for training--it takes time to learn a new technology, especially in a crisis. Plan lots of time to support people in using and adopting a new tool, it won't happen overnight.
