transwiser is the best gateway for bitCNY, bitcrab borrow bitCNY with BTS from blockchian to support the gateway,
now maybe he will meet a big problem, he can't get enough bitCNY to cover short position, and his BTS will sell to others at price 1/1.5
why he need to take this risk? he never buy BTS with bitCNY, he just do business between bitCNY and CNY,
I tell him this is a business with tiny risk, but now, I found that I have cheat him much.
is this the stable peg asset you want?
