Well, first, I suggest you do not vote for you own comments.
Until you get enough SP to equal $0.02, you don't get anything for it.
So, do not waste your voting power. Instead, find posts that you like and may give you a curation reward. Like, if you voted for this one before @papa-pepper voted, you would probably have gotten 0.008 SP. (assuming you had 100% voting power)
i did'nt know that, thanks for the valuable information @builderofcastles , i am grateful
really??? i m a newbie so know nothing..reaally informative
Yes, really. The minimum payout is $0.02
If the post (or comment) is not above that, it gets no payout.
Further, you have a thing called voting power.
You get 10 votes a day. (or more specifically, your voting power gets replenished at a rate of 10 votes per day. 5 full days to restore all of your voting power)
There are many posts about it
