"...we may need to settle open margin positions, associated financing, and/or collateral affected by the breach. Any settlements will be at the current market prices as of 18:00 UTC"This sounds like anyone who was margin long and lost the coins they were holding will have their long positions closed at the current market rate as of 1800 UTC.
What about margin shorts? They didn't own any coins so all of the shorts should be intact. Right?
What about someone who lent out their coins that were sold by a shorter? Those coins weren't stolen either.
So, every coin that was stolen must have belonged to someone in a long position.
What effect will this have on the market when they reopen?
If the shorters want out, they have to buy Bitcoin but there are 120k fewer coins on Finex to buy.
If the longs want out, their funds may be locked in USD or gone. If Finex eats the loss, the longs will have fresh USD to buy coin with if there are any for sale.
If the BTC lenders want out, they will no longer be lending coins to short.
This seems like it is going to cause prices at Finex to skyrocket when it opens.
