Very interesting! You have a fresh account so welcome to steemit. Take this upvote and keep on steeming!
I am struggeling, like you, to get those big upvotes on my posts so maybe you want to try @MinnowPowerUp where you can earn up to 30% more steem power than just directly powering up! It's a subscription based daily upvote bot that draws its power from a delegation pool. I made this post to explain the system in more depth and show how I earn over $1 a day in upvotes.
thanks so much for your advice. I will look into the link you provided. I would be happy if you share your struggle and how you plan to swim through it. If I am not wrong I guess success in steemit very much depends on unique content and good associations with other members.
