Thank you for this great feedback!

Regarding the Steempower powerup by @steemmonsters, it is actually 10%.

And our upvotes increase linearly based on the packs you've purchased. Since you bought 120 packs, you received a 3.4% vote. If you buy 80 more packs, you'll receive a 5% vote the next time.

Also, the votes are daily. So every 24 hours you're able to get another vote.

We hope this explanation was good enough.

All the best,
Smart Monsters
