to be a good trader you need discipline , the same discipline you apply to a 10$ account is what you should apply to a 10k$ account.
Have you ever traded in the market?
Trading with $ 10 fund is completely different from $ 10k fund especially trading psychology. It is possible to achieve a high profit rate when trading with a small money, but once you have achieved a large amount of capital, all of your decisions will be affected by your psychology. This is what I went through when trading.
Yes, that's a different amount but OP wasn't talking of its differences, as that is just numbers, what you need is the skills to trade because if you have that already, you'll be consistent and you can be profitable regardless of the amount you trade. Consistency means long term success in trading.
