I will try to explain it to you for the last time and I hope that this time you will be able to understand.
I gave you 5.19 SB ($ 10.38 STU).
@Tipu promises me a vote of 210/300%, so if I invest 5.19 SBD (10.38 $ STU) you should give me an upvote of 10/15 SBD (20/30 $ STU)
I hope you understand that.
