A friend once asked me what I thought about paying for upvotes, the answer wouldn't be short, I didn't have time at that moment to answer, I had already created the animation for this post but... until now I can give an answer based in my experience...
Are you gonna pay .5SBD or so for a random upvote? You don't even know how much you will get. I wouldn't take the risk. Remember that 1SBD is more than $1, actually right now it is $4,65 USD according to coinmarketcap.com. Do some math before paying something.
Remember a $2 upvote is not exactly $2, after curation rewards you may get 75% of that, so it would be $1.5; right now you would get 0.325 STEEM if your post is 100% power up from that upvote; or 0.162 STEEM and 0.75SBD if it is 50%/50%. (If I am wrong please let me know how to do the math correctly)
I saw a post a while ago reporting a guy who was spamming all around with coments like: "Pay me 1SBD and I give you 100% Upvote"; a 100% upvote sounds cool, but, this scammer had like 100SP, and his 100% was worth kind of nothing compared to 1SBD.
How to know this? just go to https://steemnow.com/ and type the username of anyone you want to know how much their 100% (or any percent) upvote is.
And the most important thing...
Yesterday I saw an incredibly sh*tty post with $28... I checked the guy's wallet to see if he was a whale selfvoting, but nope, he was actually paying several vote-bots.
The worst part is when someone new to the platform who has no idea of voting-bots sees this. What will they think?
And if you aren't new but are making a big effor to create awesome content and get a few cents and this guys are making a fortune... That hurts the community.
Or in other words, if you do something that harms the community, that will affect you too. As I said before, STEEM is $4,61 right now according to coinmarketcap.com; hurting the community hurts STEEM; and that hurts us all. If STEEM prize goes down, all our upvotes are worth less, and if it goes up, our votes worth more. So simple.
Happy Steeming!
