It's a complicated algorithm so I won't go into the details but essentially, you get roughly 25% of the vote you give as a reward.
Your current vote is worth under $0.01 cents... therefore the curation rewards is basically negligible at this point.
Even I barely generate anything from curation rewards and I have quite a bit more SP... I'd advise just trying to create good quality content and build your SP up over time.
The more SP you eventually get, the more your votes will be worth.
Good luck :)
Ooooh thanks for the info! I know the mechanics but i didn't know about my vote being negligible for having a weak sp
Actually, it depends on how many others are voting. 25% of the total payout of the post will be divided between the upvoters. So, even with low SP, you can get a decent payout, if you time it just right.
