One of the miracles of the steem blockchain is that it allows one to "give" without actually giving from his/her own pocket, by simply "upvoting".
Take for instance @fundition, which allows people to donate "hearts", which is actually another name for ... steem Voting Power !
Someone like you, @senseicat, with a vote of $3.45, you can "give" $3.45 to a project of your choosing among those on https://fundition.io/ by simply upvoting a project you find worthy of your help.
When you do that, what you are actually giving is ... "2.4 hours without upvoting" the time needed for your voting power to recover from a 100% vote.
