We all know, options and contracts are leveraged products, contract after added leverage, to amplify the returns and risk of multiples of the same, but it has a margin system, when insufficient margin will hit a storehouse, sustainable contract currently on the market of up to 125 times, that is to say, when contract direction, wave is less than 0.7% will be blowing up,

Options and contract have a lot of similarities, can buy up to buy down, when the fluctuation is bigger, its hidden leverage can be as high as one thousand times, but it has no margin system, not blowing up, for example, in the currency $40000 when you open about 4 hours of call options, the COINS on the way down from $400 million to $30000, down $10000, or 25%, if open contracts, 10 times leverage also broke, options are not, as long as the cycle, the currency back on to the more than $40000, you can still profit,
