Do you know all the upvote whale bots you can get to upvote your post? There are 4 of them right now.

That's right there are powerful bots with a lot of steem power that can give an upvote for a fee.
The fee varies between 0.1SBD to an average 2SBD. I will try to list the ones that currently working.

1. Whaleshares

How it works
Whaleshares works through the Bitshares dex so you will need a BitShares account. Then, head over to http://whaleshares.net/. Once there you enter the URL of the post you want to upvote this will generate a code that you will want to copy into your clipboard. Then, open your Bitshares account and transfer the whalshare tokens to the whale you want to upvote (whale must be signed up with whaleshares), pasting the code into the memo section. Each token is worth 1% upvote so you can decide how much weight you want to give to the upvote. Your post will then be upvoted by that whale giving you a significant boost in your payout for that post.

How do I get whaleshare tokens?
Right now whaleshares aren't yet being traded on the dex. So, the only way to get them is through the official contests and giveaways. The first of these is the logo contest announced here. Rumor also has it that there may be some given away at the Beyond Bitcoin hangouts on Fridays. Details of joining that are available here . Also, join us in the official WhaleShares discord server here: https://discord.gg/RRDzn6c. Happy steeming and hope to see you there!

2.randowhale

Here's how it works:

Ensure the post you want to vote on has not paid out or is not within 12 hours of payout
Copy the URL of the post you want Hive account@randowhale to vote on
Navigate to your Wallet
Select Transfer under Steem or Steem Dollars
Populate To field with "randowhale"
Populate Amount field with "2" (Steem or SBD)
Paste URL into Memo field
Submit
Hive account@randowhale or Hive account@randowhale1 will now place a vote with a random vote power of 1%-5% on your post!

Yes, there is now an additional account voting (only voting!) so you may see a vote from either account.
This change in voting power will result in comparable rewards to the previous settings.

3.Booster

Just like Hive account@randowhale you send X amounts of STEEMDOLLARS to Hive account@booster - whatever amount you want, it is completely up to you. What will happen next is when the timer runs out every 2.4 hours, it will upvote everyone in that time-window with a 100% upvote divided among the bidders and give a stake-based % on amounts received from you.

4.minnowbooster

As the account says this is still in beta, but it actually operating and is mostly used as cheaper option since you can send between 0.1SBD to around 0.4SBD even if you send more the minnowbooster will upvote with 100% power and the rest unused SBD will be sent back.
It is done the same way as other bots send x amount to bot with link of post in memo.
Do not expect high boost it should be somewhere between $0.50-$1.5

If you know any more whale bots please let me know as i am interested in them, and ill ad them to the list.
