So you can not say this money sucker is just a business of luck, knowledge, and the right decision. Hope for the best. For many of us here Forex trading is becoming a money-sucking machine. And this depends on our trading experience here. But still people turn it into a money-making machine with constant effort. so we must strive to join the group of people who make it a money making machine and start making money.
