Steem should always be more valuable than SBD and as such, it is not a good trade. It sometimes is a necessary trade as you stated and as I went through with.
Essentially, what I mean by mining steem power is this: If vote bots have a use, they are either to get you more views, or get you more rewards or a combination of the two. Since when you pay with SBD and essentially get back (most if not all) of the SBD, you are rewarded with steem power. I just call it mining steem power to stick with the crypto theme.
I hope that clears it up.
I did not get flagged... but I also did not hit the trending page. That is one costly move!
i'm very sorry for such a late reply.
indeed hitting trending page is very costly.
do you break even on using bots?
