Whuddup! I can see you're new here so I wanted to personally welcome you. This deserves an upvote and I hope you will some day do the same!
I am struggeling, like you, to get those big upvotes on my posts so my advice would be to give @MinnowPowerUp a go as you can earn up to 30% more steem power than just powering up! It's a subscription based daily upvote bot that draws its power from a delegation pool. I compiled this post to explain the system in more depth and share my own experience in earning wupvotes for over $1 a day.
