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.

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.
