I owed you 100, I give you back 70, ok? 70 is close enough to 100.... don't you think??
If that's how you see it, then just sell your BTSX when your stake becomes liquid. I think there will be some scaling there so it won't be as long a wait period as you might think (we'll see).
Personally, I didn't see any DACs coming up that were worth more than a new stake in BitShares X. Did you see anything good beyond Music, DNS, and Vote, which already had their snapshots that gave you much greater than 10%? Stakes which are being honored again in this snapshot, mostly going to PTS/AGS holders? Nobody's working on BitShares Me and who knows what's happening with the Play/Lotto one (the third party Lotto DAC died already; nobody played it). I think if someone comes up with a video DAC, they're going to build it into Music or use that chain. If there's a stock market DAC, it'll be part of BitShares X or in that family chain. These are the most profitable ideas on the blockchain now; if there's other low-hanging fruit, it most likely will be progeny of these. So your PTS and AGS won't be as valuable there anyway.
To me, this is a merger where my 100 shares of Alta Vista just became 80-90 shares of Google.
