I invest in the US market, and there is at least one advantage to the falling exchange rate

‌
I had about 20 million KRW in realized profits in the first half of the year.
Yesterday, I sold some stocks that had large foreign exchange losses and bought them back,
effectively reducing my realized profit by about 10 million KRW for now.
If I reduce it once more in the second half,
I might not have to pay any taxes.
I won't pay taxes, yet my assets in USD will increase.
Since I am investing with dollars exchanged when the rate was at 1,200 KRW,
it isn't a huge burden.
I plan to exchange more currency once the rate drops back into the 1,200 KRW range.
