The discussion in the thread you linked appears to be VERY interesting (judging by google translate)

but also impossible to follow/understand (if using google translate).

As a witness & committee member, I really wish it was in English (or that I spoke chinese) so more of us could participate.

1. Charge the mortgagor Margin Called（mandatory liquidation）deal fees，these fees will be used as the fund of Black Swan.
   
    Charge the mortgagor Margin Called（mandatory liquidation）deal  fees, charge 5% or higher , we can set an adjustable parameters K, of cause, need to discuss charging bitasset or bts.
   
    The bitcny supply has 0.6 billion in the peak value, now has 0.15 billion, charge 5% fees from Margin Called, as the Margin Called happend over and over again, we will charge 30 million bitcny or the equal value bts at least, after july updat, these fees can handle the Black Swan very easy.
   
    When the collateral ratio is 120% or 115%, the fund of Black Swan will buy or take some debt from the mortgagor, make the collateral ratio was not in margin called.
   
    Every bitasset can charge fees from their margin called independent, and will have the corresponding fund of Black Swan, don't need the public or privat fund to participate in, the probability of Black Swan will be very very low.
   
    Maybe need to design the automatically operations of buying or taking some debt from the margin called.
   

2. Change the MSQR to 105%(reducing the deposit fees of fiat money);
   
   Several Stages of the margin called which was bought initiative or passive.
     first；hot market sentiment，initiative bought margin called；
     second：stable market sentiment，initiative bought margin called ；
     third：not stable market sentiment，passive bought margin called，when the market rebound，initiative bought a little；the price of the DEW market will be suppressed by the margin called price.
     forth: crash or bear market sentiment, no body buy the margin called, when the market rebound, will buy the margin called occasionally; the price of the DEW market will be suppressed by the margin called price.
   
    So, 110% MSQR is not the good way to handle the margin called, and only have little use to make a effective deal, and it has a vey negative effects which will Crush the market depth very quckly, and can't delay the speed of Black Swan coming.
   
    So, i suggest the witnees to adjust the MSQR to 105%, which will reduce the deposit fees of fiat money, when the market went down, the supply of the bitasset is not the key factor of the deposit fees of fiat money, the public market operations only have little effect to it.

3. Force settlement offset dynamic varying as the collateral ratio；
     
     The Suppose formula from bitcrab: Force settlement offset=（ratio-MCR)*0.04

     Personal：Force settlement offset=(ratio-MCR)×K(K=adjustable parameters）.
                 
              when K=0.04，the 275% collateral ratio will have 4%  Force settlement offset.
              when K=0.05，the 255% collateral ratio will have 4%  Force settlement offset.

4. Change the collateral ratio to two parts: Margin Call ratio（175%）and Maintenance collateral ratio(185%).
   To prevent: when the price have a little fluctuation, the collateral was be boom!!!
