It all depends on you. not everyone can do it and it takes loads of time to become experienced at it.
I have some friends who did it as a hobby .but it pays them really well. They use Forex trading to subsidize their salaries and live a good life. The one chap has been doing it for around 6 years now and normally doubles his initial investment by the end of the month. He does loads of small trades.
I have thought about doing it, but decided against it. I think spending my time on Steemit will eventually be more beneficial and pay bigger rewards in the long run.
Yes, definitely, but only if you are good at it. Otherwise it's the fastest road to hell. You can loose everything in a second.
Forex is not easy. It looks easy, you can get carry away by the big wins but that's not for everyone. You have to learn a lot and study the market before you go live. Make sure you invest a sum of money you can spare and don't put your life and family at risk. Start small and see how it goes. Don't get greedy, Use stop ans limit orders.
