Just to give someone who doesn't live in these markets some idea of how volatile they are > Goldman Sachs Group Inc. demanded some clients set aside collateral equal to 100 percent of the value of their trades, people familiar with the investments said last week. The guidelines are inclusive of other margin requirements such as Options Clearing Corp.’s 44 percent, required to clear contracts traded at Cboe, and the 47 percent CME is demanding. > Interactive Brokers Group Inc., which has said it handled 53 percent of the first day’s trading in Cboe’s bitcoin futures, will require a margin of 50 percent for long investments, and about 240 percent for short selling, based on current rates For a more typical futures contract like say wheat, its common to have to put up 5 to 15% margin. SO there isn't alot of leverage that you can get from these, which is almost certainly a good thing:)
