I have had arguments with people concerning this topic, because they feel that with more capital they will be profitable, and I certainly believe that even people in this forum fell so too, and that has totally changed your mindset and willingness to learn.
First of all trading is not just all about money, although our initial aim is always to make money from trading but when you are now into the game you will understand that there is more to life than just money. Everybody's mindset is either positive to them or negative. Imagine having a $50 account and you blow it, what makes you think if you have a $50,000 account you will not blow it, the only difference between these two accounts is the time taken to blow it as long as you don't have the required knowledge to manage them.
It is even much better to test your skill and to straighten your emotions and psychology with a small account and after that purchase a prop-firm.
if you have the required knowledge no matter the amount of capital available you will be able to handle it and grow it but when the knowledge is not there no matter the capital will be able to blow it.
People that grow $10 to $10,000 are still humans like you but knowledge is the difference.
Don't just chase money, chase knowledge as priority, that's why I said trading is not all about money.
When a person is able to handle the little money with time and thinking, then he has equipped himself to handle bigger responsibilities. I have witnessed many traders who have just started in trading and would strive to grow their initial large capital by doubling it instantly without having the knowledge of how the market and their position operates. Money is good but that will make you more frustrated once you fail to understand how to behave when things are not the way you wanted them to be. Or, again, when you are sufficiently accustomed to think clearly, are not easily excited by the passions, know how to make a stop, well capitalized you will not be enslaved by this capital.
It is easy to forget that what we are struggling against in this world sometimes is not only graphs and numbers but ourselves. and if you have failed to master yourself then there can be no money that can hide that error. Based on this we are in a position to understand that all that we do in the exchange does not come without the knowledge that is fit in getting profits easily. When we have much capital and lack trading skills then without a doubt we will lose capital that we use to trade.
