I remember realising this as well when I delegated my first STEEM Power to minnowbooster. I got shocked as well. I also happend to not pay attention to my bandwidth, so I got scared for a little while when i saw my bandwidth in minus for a hour.
But I believe that delegating is a great thing, as I am giving my responsibility to upvote good post, to someone that actually can make a difference.
Are you regretting your delegation too minnowbooster? Or am I not understanding correctly?
I was just playing around with it and learning. Once I build up a bit more SP I will probably give an ongoing amount to minnow booster or other helpful bots that help build the community.
Great to hear! I wish you best of luck in your STEEM future!
