Looks like IB will set the margin at 100%... possibly more or restrict shorting futures.
"Duffy said CME may institute trading halts at 20% swings in the value of bitcoin to smooth out some of its volatility. Peterffy, however, argues that that might not be sufficient to protect against severe moves within, which aren’t infrequent occurrences in bitcoin trade."
Trading halt at 20%... might as well do auction only, you'll end up trading more
There's no way that 20% trading halt will work, that will be hit constantly and disrupt trading in the futures. Peterffy has good points....
