I know many guys who have been making 100% plus on sub $100k accounts for 20 years. But their accounts never grow.
What you know is irrelevant in regard to my position.
But I can tell that I make more then $2000 a week and my daytrading account is beyond $100K.
My account grows as I spent less then I earn. The time that my trading account was the biggest part of my investments is already long gone. All profits that could not be reinvested in daytrading are invested elsewhere. I spent nothing from these investments and can still increase them as I don't spent all my daytrading profits.
