Bts system can only be short after the feed price reform
You can do more and short before you reform.
Now that bitcny is stable, why not make a way to do more?
My method is to add the borrowing function to bitcny to bitcny lender interest.
The bitcny mortgaged by bts should be loaned according to the interest of the day like zb
The mortgage function of bts is the role of the printing machine rather than the interest-free loan.
