The parties who "benefited":
- People who withdrew XCP that they bought before closing (this is the 7000)
- The hacker, who is up +80BTC

The parties who were unaffected
- People who did not have XCP on poloniex

Ideally, people who withdrew would deposit funds back into the exchange, the BTC would be redeposited, and all trades reversed, which would result in no one gaining or losing anything. However as this is not actually practical, the exchange is currently soliciting donations to try to cover the remainder.

That's the current fund situation right now.

Thanks for the good assessment of what happened at the exchange.

I'm encouraging those who benefited from the low XCP prices and withdrew the XCP to offer to return it to the exchange.

It might have looked like an fortuitous turn of events in your favor. However, you now know that it was caused by a bug in the protocol. It is the right thing to return what was not really yours to begin with.

If you decide to keep your windfall, know that you are benefiting from the misfortune of someone else in the community.

If more than 70% of the shortfall of XCP is returned to the exchange, I will personally donate 100% of all of the XCP that I would have lost (ie all of the buy orders which filled during the dump) to a bounty or donation fund for XCP.

Edit: I decided to lower the barrier from 80% to 70%

These are the address of the people that withdrew XCP before closing of poloniex (these are the "7000"):

I think Busoni needs to check if these account are holding BTC and "hold them" + check if these accounts have xcp left in poloniex and subtract them. (of course after checking that these users benefited from the 35,000 xcp sell)

these two address: 17yzh4iz8dsYRgWWkm83HYHZtgXqC31rzC Received 3568.9 XCP
and 1LArq4ZstbNo2Dcq3dg7QdtoTpvizsX52h Received 1183.7369884 XCP

withdrew total of 4753XCP = 67.9% of the xcp "missing"

I think we should make an effort to match these address to bitcointalk users it might help to convince them to return the xcp to poloniex

Agree on this.

Also if there are any loss after this, it can be shared between poloniex, xcp developers, community and poloniex account holders
