If you start with higher amount of money and you know the market very well then you can of course earn a lot profit within short time if you're good at trading but if you're new to trading and you're still learning trading and aren't a professional trader by any means then it's 100x better to start with low amount and learn trading in the best way possible, and one who learns trading very well can really make some good profits even by starting with a small capital, but that takes time and patience.
