If we talk about Forex and trading, then this little money can be invested in trading. A beginner just doesn't need large investments just yet. And to test your strategy on a real account after a demo account, this amount of investment will be quite sufficient. In this way, a beginner will not lose much, but can understand and feel the psychological factor in trading, which is not present on a demo account. By the way, in fxopen, when opening an ECN account, it is possible to open it for such a minimum amount.
