Hello. Thanks for stopping by and asking really good questions. Let's start from the end and work backward to the beginning of your comment.

Kryptonia - See my post here
This is a platform where you get another crypto currency for completing tasks like visiting people's Steemit posts. In return, you can pay them in these coins (which you earned for free) to visit your posts. Cool system. Use my link here to register

I will be writing a post on low-cost voting bots with profitable payouts. However, here is one of my favorites that I like to support - @goldenwhale. You can send them as little as .05 SBD and get a profitable upvote. I don't recommend sending more than .07. I use them even though I don't need their upvote because I like to support small bots. Another one is @mitsuko and they even give you a resteem.

Keep reading my posts over the next few days and I will be giving some details of my upvote strategies using bots and pay for vote services as well as resteems. Also, go back and read my other posts about tools and strategies. These are all titled Steemit Essentials and Steemit Strategies.

I'm very pleased you stopped by and hope to see more of you. Let me know when you have questions. All the best to you.
