So I decided to try out 
What Is It?
You may ask yourself what is this and how much is it? Well you can send 2 SBD to randowhale with a link to the post you want them to upvote and it will upvote your post with a random chance of getting a 1% to 5% vote from them and you can loose money or make money. Ive seen it a lot on other peoples post and it says something like this
This post received a 2.4% upvote from

Trying It out
So I sent my 2 SBD to randowhale and had them upvote this post and lets look at the results from it.
So as you can see the post worth went from $0.08 to $4.63 with that one upvote being worth $4.55, with that being around 3.9 SBD but as you know you should only expect 75% of your total post worth because of the curation rewards. So with that said I used it on a post that I could get the results from and see how much I got back.
Past Payouts $4.42
- Author: $3.42
- Curators: $1.00
So that $3.42 is just below 3 SBD so from that you could say I made 1 SBD back but you also have to take in consideration that its either a 50/50 payout or 100% power so I chose to do 50/50 payout to see how much SBD you get from it. With that said I got
1.864 SBD- $2.1619
1.071 Steem Power-$1.6135*
as the results and that comes out too $3.7754 in USD and I originally put in 2 SBD or $2.3236
So I made around $1.4518 from using the service.
Conclusion
Its a fun little thing to spend your SBD and get a little bit of profit but you also have to take in consideration that you can loose some money because of the vote you get from the bot, so I would say if you have extra SBD you dont use go test it and see if you like it yourselves but if you were like me and spend all your SBD on this I would not recommend it until you have extra SBD to use.If you want to go check it out and read about it more in depth go to the link at the bottom of this post. Tell me if you ever used this before and if you still use it or not.
