so i will start with a question: do you know what voting power is? (there is not right and wrong answer to that) it's more like in order to tell you a bit more about the system
Also an advice would be just to upvote whatever you want. Because someone made you a ''good'' comment doesn't mean it's a guarantee upvote. In my case sometime i give 0.01$ upvote to every comment ( except the good post ones) others i just reply without giving nothing and in some cases where i like so much the comment or it is so to the point, or even made me rethink some things then a 0,06-0,10$ upvote and even more will come
Voting power is the reason why I said I could give a full upvote to 10 other people per day and more if I gave lower upvotes.
