If I might throw in some advice, I gached 8 INT Red Marker as well and it didn't sell at 500m for 3 days, not at 450m for 3 days then at 420m. Hope that helps to get an indication!
C/O as of now is 400mil, if there is not another offer within the next 2 hours its sold Nevermind it is SOLD, if an admin sees this thread please close it.
