For those who think that deducting 15 points is still too little, I truly have no words.

I guess you haven't graduated from elementary school if you can't even calculate.

To make up for a deduction of 15 points, you would need to double your trading volume every day for 15 consecutive days.

For those who think that 15 points is insignificant, do you really believe it's easy to earn back those 15 points?

Don't think that brushing up 15 points every day will net you an additional 15 points; don't forget that during the 15-day cycle, your previous scores will also be deducted.
