CME has just increased their margin requirements for shorts to 500%.
Edit: for those not fond of math, you need to post $95,000 margin to short one paper bitcoin at $19,000.

Where can we see this?
I understand fuck all about futures but it sounds cool. Or doesn't. I dunno.
Sorry this might be bad information. The only authoritative source I can find says 43 -47% margin. Carry on.
