For anyone reading, I bought a @tipu upvote for this post, and it was immediate and profitable.
I sent 7 SBD to @tipu, and received an upvote worth 9.739, which after curation and creation rewards will amount to 2.97% profit.

I do this roughly once a day, and its nearly always 3% profitable, meaning that across a year, I will compound that investment by buying upvotes, with the profits...

This is a big deal. Look into it.
