thanks for answer the question, I'm sure a lot of people are wondering.

thank you so much! 😀 It had been bugging me! Lol

I confirm @akrid 's answer. It's 100% powered up. It signals that the author believes in the post or at least it's their best post at that time. Some people who don't post a lot may have this symbol next to their post bc they don't mind using that much of their voting power at the time since it'll regenerate by the time they're ready to post again. It was a good question. Gave ya a follow :)

Thanks @showoff! I didn't know you could adjust those settings.

I was also wondering about that. Thanks for your question!
b.b.

it is good or bad

Thanks heaps @akrid, but does anyone know what's the benefit of 100% power up vs 50/50?

If the price of SBD is below 1 USD, it may be more profitable to use 100% power up.
