How much are you actually needed to invest, when first starting out trading in Forex? Can you get your investment back after a while?

Invest what you can afford to. One unfortunate side about online Forex is it's not directly linked to your bank account. In many cases, funds can take 2-3 days to arrive even for a verified account. Recreational trading is a good way to start. Once you develop some confidence in the trading platform you are using you can make a more serious investment and start making real money that will make a difference in your life.

Very good advice for sure. I would say invest small, when first starting out, until you get the hang of it. Once you have experience, you can go higher.

There are some platforms that go as low as 10$ initial investment. Definitely worth it, just to check out Forex trading in general.
