The green is how many people wanna sell SBD.
LOL.
Conversation with Satoshi regarding SBD:
Q: What do you think of SBD?
Satoshi: I don't trust SBD being this high...but there's no reason it can't be that high or higher.
Q: Why don't you trust it?
Satoshi: I think it can crash at any time. But at the same time, I think people could keep it this high.
Q: Why can it crash at any time?
Satoshi: It's supposed to be $1. It's only lower pegged though. So it really shouldn't be this high, but it can be.
Q: Who says its $1? The Steem developers?
Satoshi: It's got various mechanisms to keep it above $1. And all over Steem it's programmed as if it's $1. The developers had to update various things due to its rise.
And then he dissapeared...but I guess that's nothing new.
