For me, starting small from starting big is not different at all, I mean you all both starting however your point of view is still the same regardless of how much you have in the start. For example, you have a $100 as a starting fund and the other one has $1000, so if he bet $100 on his first trade while you bet $10 on yours, it's just the same.
You don't have to compare yourself from others, what's important is you know how to manage that starting capital of yours to make it big as the time passes.
Capital really matters in trading and if we think that to start big amount in order to get more profit? It is still uncertain...but the possibility is that you might lose big also if you are not doing well. But to start small amounts while learning is in great advice by most, I think we need to follow it and in fact, we can top more funds if we are too prepared and have enough knowledge.
But anyway, it is all about our choice, we can risk more and start huge amount if we can afford to lose, nothing wrong with that provided that we don't blame the market nor the others.
