It's based on which ones you upvoted and by how much strength.
If you upvote comment A with 100% voting power but comment B with 50% the rewards of your beneficiaries will split it 66.66% and 33.33% towards the comments. So it's all in your own control.
To avoid wasting mana as a low HP user, u can instead direct @commentrewarder with 2% and 1% votes for instance and save your mana on other people's posts instead since no matter if u do 1% or 100% the actual comment won't get any rewards due to the minimum threshold requirements for the blockchain to generate post rewards.
Are you saying that with 1073 HP that I currently have because I'm new here this wont actually generate any rewards for commenters of my posts if I use the @commentrewarder service because my HP is too low?
No, commentrewarder itself will work to tip the rewards generated by your post, but your own votes won't be able to get the comments to the minimum value required to give them rewards from your own vote.
You are also not voting with 1000 HP as you have 90% delegated out, so your votes are only worth a fraction of that.
Yes, I understand. And you will soon see, given the position I'm in, why I might soon be using the Commentrewarder service all the time.
dunno what that means but go for it I guess
It will all be explained, I promise.
