That is a small contract. Though I guess if it goes up it will get bigger!
As a IB customer, it makes me sleep sound when Interactive Brokers founder has a strong sense of risk. Bitcoin daily fluctuation can be >20% per day. With highly leveraged futures, the broker can be pulled down with their clients.
Exactly... that's why I think the margin should be at least 20%... probably more. When it becomes more clear how liquid the futures trade and perhaps options, the margin could come down IMO.
I would prefer bitcoin futures to be unleveraged given its very high daily fluctuation. If IBKR were to offer bitcoin futures, make it unleveraged, please. Frightened of a MF Global or Refco scenario. Alright, make it 80% margin. Sounds out of place to have unleveraged futures. Might as well buy ETF.
