Hm? Where is a logic?
First of all, self upvote is 100% transperent - I'm doing nothing prohibited by this blockchain, and doing it openly.
But even then... I don't ask you to send me 1 SBD or something, do not try to make some trusted deal with you. So I do not need your trust anyways.

But SBI needs trust of their peers, cos they getting real money for a far-reaching promises, with no way to force refund in a case if these promises are broken in any manner.

Ergo: my question is a good question, even in case I'm myself is a totally malicious person with a bad intentions. True?
