I saw big margin call had happen on these three market,
but the share holders seems refuse to take the 10% profit help others quit short position.
you need to know when the price continue drop, black swan will happen in these SILVER,
then these SILVER you hold will lose the value it can be.
sell your SILVER, take the 10% profit, this is what you should do, or your SILVER will not worth 1 real SILVER after the blackswan
