For those of us with little money to invest, I suggest leasing delegation through @minnowbooster. I have just started doing it and my little 0.01 upvote is now a big 0.10 upvote! I think this is a cost effective move when you are a little minnow and may not be worth it as you grow.
It's amazing how much difference this extra sp makes in my results. I plan to keep leasing the delegation up to about 5000 sp - then hopefully my success will be all I need :)
Thanks for such a great example for the rest of us.
Totally agree, leasing delegation is also a great way to become influential on steemit 😀
