Personally I would start an upvoting "crowdfunding" campaign for such as:

• Poor people
• Water donations to Africa etc.
• Invest in biotechnology for cure and genetic disorder research and projects for ecosystem in earth.

To start such campaign, users must upvote an post round.
Lets say you start the campaign at 10 January and let everyone kown there is such campaign. The fund goal is X SBD and all you ask is a max vote of X %. In the end with all your steempower earned from the campaign. Everyone who voted X % voting power, get an upvote of X %.
The upvote period starts from date 1 to date 2 and you have to send an 0.001sbd message to the campaign account in order to get an upvote. You will get the upvote from a comment.

This way people could get back their voting investment without really donating a whole. And could make work.

It is just an idea but I guess you know what the concept is ;)
