payout just came through ... can we freak out now ?
sadly, things like this happen to be the norm on middlecoin. Hopefully, we'll get an explanation but I wouldn't bet any money on it.
I would bet it has to do with Crypsy halting Doge trading a little while ago (see posts linking to thread about it a few posts up). The values in unexchanged are derived from Crypsy even if H2o doesn't trade it there so.... I'm betting we'll see it jump back when Crypsy resolves their issues.
