I don't understand this idea that big leverage = immediate blow out.
If you're careful, why NOT trade their money instead of yours? What's wrong with only having to put up a fraction of what you're actually trading? I think it actually makes things easier because you're able to make more profit on smaller, safer moves, rather than either needing to have a gazillion dollars to do the same or going balls to the wall to try to make the same profit with smaller amounts of money.
