It's not a scam but yeah, like it was mentioned in one of the previous responses, reminds simple gambling very much. The main idea for forex is getting money from difference in exchange rates of foreign currencies, such trading is always made in pairs (like EUR/JPY for example) and your profit will be always based on the current prices of the currencies. And these prices can change fast and unexpectedly, you can't know exactly when that happens so it's very easy to lose your capital or earn during some months almost nothing
If you want to try this market too, then I recommend you to find a safe broker and start with a mini account/small capital, you'll see after some time if it's a good choice for you. But I should warn you that there's a great lack of teaching beginners inside this system so you'll need to learn very much independently, without extra help from others. Also be careful with brokers, there's much scam among them, choose only reliable ones from regulatory agencies lists
