RE: Steem Account Gift Certificates Idea
This is actually a really clever idea. I like where you're going with it...although, some will not ever cash in. So I guess Steemit could just take the floating cash. It wouldn't have to go back to the buyer. Although that would be more consumer-friendly. Maybe it could go into the buyer's account as SP or something, after a certain period of time.
So the nonce would be purchased at point of sale for $20, but the interest would increase as though the account already existed. And that would go to the new owner in SBD for the current value of SBD at point of redemption, or it would go to the person who purchased it, for current value of SP at point of redemption.
Does that make sense???
So it would say something like:
"This voucher will allow you to claim a Steem account purchased for $20. Go to this link and find out if your value has grown, and cash in before it's too late!"
Like you say (in the other comment) maybe 28 days is too little, but I think it's fairer for them to be refunded after that period rather than added to a treasury of some kind.
I like the temptation component of the 'go and find out how much it's worth' thing!
