It's true that nothing is risk free and even in the spot, the risk is there and even in accumulation it's also there. But, the risk has been minimized with these kinds of way of holding because the pressure and it's lesser risk than the actual trading. And it's even more less if we'll have the futures trading. People think that the better risk is more profitable, it's true but in the long run it's still best to have the lesser risk to do and that's why more traders are losing even with so good strategy. You'd see those that choses to stick with holding and investing.
