A long time ago when steem was still just months old it was debated to hide the payout amount until it was paid out. I didn't think it would make a difference and Steemit is all about transparency. So it would go against the constitution of the platform I think.
I didn't know about that. Indeed, I can see when the payout was delayed 24 hr, it was still more applicable, now with a delay of 7 day, it would be too surprising too.
