Not common. Because both industries in developed countries and ourselves know that it is not advisable to borrow money to speculate in stocks and futures. People who borrow money to speculate in stocks and futures want to smash themselves and their families into pieces as soon as possible, rolling in the deep. Perhaps only one in ten thousand people may be spared and have no luck. Therefore, even if someone borrows money to buy stocks and futures, it is a minority and will not be very common.
