10 euro for free
Just want to recommend small Swedish company Trine. They are crowd investing in solar power in Africa to help end energy poverty. It's like micro financing. Right now they are offering 10 free euro credits to first time customers. So if you invest at least 25 euro (minimum amount), 10 of them will be for free, and you will get an interest on the money too. Actually earning a good return on giving villagers access to solar energy instead of kerosene, which damages the environment and the people who breathe the fumes!
