Hi, everbody
I am thinking a new way to create bit x(bitusd)----public bid
bitusd ( bid )
bitusd created by public auction weekly. if bts=usd100, bob offer 0.01bts to buy 1bitusd ,alice offer 0.011bts to buy 1bitsud, alice win.
bitusd (spot)
alice can sell his bitusd on the spot maket.
bitusd (margin )
difference level difference risk pool, if any pool broke, doesnt affect others
level 1 (1:1)
level 2 (1:2)
level 3 (1:3)
level 4 (1:4)
...
bitusd (futuer, futuer option,swap,libor,note,bond market)
...
now my grandma can save her bitusd safely, do not worried about "short positions call margin"
