Yeah sorry, boosting is just the word they use in the eSteem app.
If you post an actual post using the eSteem app, in the top right there are 3 dots. If you click that you can get to the option "boost" and "promote" among some others. Boosting means that you pay the eSteem team with the points you've earned, to upvote a post that you wrote on their app. They then will have a curator look at it and decide if it is a good post to vote on. If they like the post you will get the upvote value you chose. If they do not like the post, they refund you the points.
The upvoting does not work for a post you have created on a different application such as using the website hive.blog so that is one thing to be aware of.
Oohhhhh. I understand. It's a good thing. At least they can refund you if they don't like it. Well I am happy to know all the privileges I can get using the app. Never knew uptill now.
Thanks dear🤗🤗🤗
