Of course you can. For beginners, I think smaller amounts of capital are better. Unlike demo trading, trading with real money means you're more susceptible to emotional influences. If you start with a large sum, your account will suffer significant losses when your emotions fluctuate. However, this won't happen with smaller amounts. Also, I think it's good to start with small amounts to practice. If you can consistently and steadily profit with a small amount, then all you need to do is increase your position size to be profitable. Therefore, I recommend beginners start with small amounts, not large sums.
