Forex trading is never a scam. What you need is the right skills. You need to experience too. Yes experience the downsides of trading to (I hope not badly) before you can keep your head straight. I know some of my friends that made it through trading.
It's not scam! Things you should attribute to scam are platforms out there. So many fake platforms there clamouring how their website will get you trade and profit a lot. This at the end of the day end up being a big lie.
You will lose the enticing bonus they give you, lose the money you invest and a good time of yours.
Trading is not a scam, what you should be careful about is trading sites.
When you get a good and legit at form, with the right skill and experience, you are good.
