For @booster and @bellyrub it depends heavily on how many others are voting in the same cycle. I just made 15SBD upvote with @bellyrub sending just 3SBD. I got a 66% upvote because only two other lower votes were in. That was lucky but highly unusual. My experience with both bots is that you will make little or even loose some when you are not careful.
My favorite upvote bot is @minnowbooster because you know exactly what you will get beforehand. You can check it here: https://www.minnowbooster.net/
It is currently low with coting power but they changed the rules and it will improve again. Check out their latest article.
And @randowhale is a total gamble. I think less than 50% chance to make a profit. So in average you will always loose money. [...] I double checked it: It is a tiny bit higher than 50% actually at the moment. But with this you will never make a good profit in the long run.
This is my list of choice in that order to use my SBD on:
- @minnowbooster
- @booster (Always check for current pool and current voting power(don't use the VP from the first link, it doesn't work
- @bellyrub
Thanks for the advice, my dear.
Double check that comment. I edited a bit more information to it with some tips.
