hey @thecryptokid-yt,
yes, that's good for you.
We're automatically calculating the curation based on the age of your post so that you're getting the right amount.
More curation = More votes
But always keep in mind that promotion shouldn't be done purely for making money. The ROI is to minimize losses. The goal for promotion should be to get your post seen.
And even if you'd make a net loss right now, due to whatever reasons, chance is there that it's a big profit in the future.
Think long-term, not short-term.

hey I recently sent 2.5 SBD but did not get 15% ROI since the post only got 2.61
That's not how ROI works. You're getting ROI based on USD. Check this post out: https://smartsteem.com/promote/buy
I sent another 5 SBD AND YET AGAIN DID NOT GET THE GAURENTEED 15% ROI
You are getting a great deal. You should be using bots to promote your content and not for ROI. If you end up with a positive ROI that's a great bonus.
Other platforms such as Facebook or YouTube simply take your money and offer no money returns but just promotion. Steem bots give you an upvote as well as the promotion. Even if the ROI turns out to be negative, it is still far better than what other platforms are offering.
My advice is, make the best posts you can and then promote but in moderation. Over time you will build a solid following and your content will naturally improve with practice.
I have sent you 25 SBD but still no upvotes
