I think replies to replies are not included in the bounty calculation. Next week we can try to test this. If you don't upvote my first comment but only my reply.
Laat week I had this question:
I do wonder about 1 thing. Let's assume you upvote 2 comments from 1 user. Will that user receive 2 separate bounties? Or will that add up into 1 bounty pay out?
I think the answer is in one pay out. But I'm not 100% sure.
Oops, I already upvoted it :) I'll try to remember for next week.
It would make sense for the upvotes to be added together into the single bounty payout. I've not checked the math in the reply that is posted by @steem-bounty on payout, but it does look like that is the case.
When split between so many commentators, the 5 SBD doesn't go particularly far, but every little helps I guess :)
Your post is really popular. But there are also bounties where 5 Steemonians react per 1 SBD. If the author then gives upvotes with different value, one could earn a nice amount. Especially if you already planned to read, react and interact.
I think the fun part is the best part. But in the coming weeks I will participate in a few bounties.
