JamesLT is right mathmatically.... It is much easier to make higher percentages on $25,000 compared to $100,000 because 10% of 25,000 is $2,500 and 10% of $100,000 is $10,000. So the larger account would need to make much more money than the smaller account.
On the other hand 10% is 10% If you are all in on your account dollars numbers do not matter it is for the people who prefer not to be all in that are affected by the dollar numbers.
Side thought if a person has a negative amount doesnt that mean they have to lose money to make a high percentage?
-1,000 X 10% = -100 :)
