$1500 can grow to over $40,000 in 4 months? Doubling a small principal depends on one word: "stability"

Starting with $1500 and reaching over $40,000 in four months—some might find it hard to believe, but this is the real result I achieved last year while guiding my brothers through practical trading.
Recently, many people have asked me how to double a small principal. The method isn't complicated at all; the hard part is whether you can stick to the rules long-term.
My brother never touches high leverage or gambles on emotions throughout the process. It’s a bit boring, but he genuinely managed to grow his funds.
His first step was not to rush into trades. He split the $1500 into three parts:
One part for short-term trades—take profits quickly and avoid holding onto positions;
Another part waits for clear trends—absolutely no trades on assets like LIGHT or SQD without obvious room for growth;
The last part is treated as if it doesn’t exist—no matter how itchy his hands get, he doesn’t move it.
I told him, splitting positions isn’t conservative; it’s to ensure you never get wiped out in one go. Keeping the principal intact is the only way to have a chance to double it.
The second step is to only trade when the market has already shown signs of movement. For example, during PIPPIN’s consolidation, he simply closes the software and stops watching the charts.
Most of the time, the market isn’t worth trading. The real profit comes from the main upward move after a breakout.
And as long as there’s profit, he takes some off the table first—prioritizing safety—then lets the remaining profits follow the trend.
Discipline is paramount. Cut losses at the right levels, reduce positions when profitable, and never over-hedge losing trades—afraid of deepening the pit.
In these four months, what he did most wasn’t trading actively but waiting patiently.
While others were cutting losses repeatedly, he stayed in cash and observed; while others chased high prices in emotional frenzy, he had already exited with stop-loss.
Actually, whether a small principal can double doesn’t depend on being aggressive but on being stable.
Stick to the rules, and money will come naturally. Fail to do so, and even a large account can be wiped out.
Turning $1500 into over $40,000 relies on those seemingly “stupid” rules—being able to stick to them consistently.
