For the domestic market right now, day trading is the only answer

Even if the market is sideways, if both the KOSPI and KOSDAQ show daily fluctuations of more than +/- 2% based on major indices, long-term investing is guaranteed to trend downward. In other words, if these fluctuations continue, a downward trend becomes synonymous with a sideways market.
Leverage-related stocks are essentially just deleting money.
Right now, the volatility in all stocks is massive.
In the past, people used to talk about "Samsung hitting the upper limit" (Sam-han-ga) even if Samsung Electronics only rose by 3%; and this wasn't even that long ago—it was just two years ago. Look at how stocks are moving now.
I feel like as long as Trump is "shooting" (not just meaning actual war), the market will definitely move like this, and for those holding stocks, it's death.
Even if you aren't a professional day trader, I believe those who respond to the market primarily through day trading are the ones smiling.
If they were to even block short selling, the volatility would be even more extreme than it is now. Good grief.
