@lays do you have another account where you are doing this successfully? I am a big user of upvote bots like the ones you mentioned but you can't just throw $250 SBD into them and get 300 - 400 SP so easily. You need to do a little at a time and it takes a while.

I recently built a site http://www.steembottracker.com where you can get more details on all of the services you listed and more and you can see how and when to get a profitable return.

I agree you can get to 10k Steem Power from a relatively small investment and using the upvote services wisely is a big part of that, but I would add that if you post good content it will help speed up the process considerably.

I'm trying to do the same thing currently with around a $500 SBD investment and would like to help others do the same.
