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.
It's not only the psychology but remember when there was no liquidity in the market and it will be much more difficult to liquidate your money too.
Trading is about how to combine all of the things related to the sentiment, psychology and fundamental to be analyzed by us to get how potential a coin.
