What I like about using Steemit to fundraise is that you have a variety of options with regards to donating. If you can afford it, you can donate Steem direct, but if you can't you can upvote and that costs nothing, but a bit of time to replenish. Then the funds can go straight to the place they're needed without the concern that some will get eaten away in the costs of getting them there, or skimmed off the top.
