and you lose money 4x as fast on the flip side!
many people blow up by overdoing the margin and getting caught in a bad trade.
The "many people" you refer to are ignorant new traders who have zero discipline and are trading a non-existent edge. However, if you've taken the time to read the OP's prior posts, he seems to have a "system" that is net positive. You're comparing apples to oranges.
I know a couple of prop traders who now trade with a retail broker using 4 x margin. They're netting more than they used to trading prop.
