In the traditional financial markets it can be very difficult to trade a falling market due to regulations that try to prohibit this behaviour. There is also a bias among some investors that betting on a falling price is somehow unethical. That’s simply not true. Prices will rise and fall with no regard to your ethics and profiting from a falling price is still a profit at the end of the day and the asset is not going to care or be affected in any way by your short trade. For the first case of regulations there is a simple way to avoid these, and that’s by trading CFDs on the asset rather than the actual asset.
