I saw this post while I was going through articles on bandwidth and I thought I'd mention this: even though my Steem power is 23, I can only give $0.1 upvote maximum and because of the voting power after it crosses 50% it becomes 0. I have had issues with bandwidth as well so I had to stop using it for a while so the voting power was back to 100 otherwise it looks like an empty upvote where I'm getting value but not giving anything back. I don't know if you'd read this post since it's 8 month's old now but I'd really appreciate if you could help me out here. Thanks for providing value to the community!
