Which trading is risk-free?

Could you please elaborate on the statement "Which trading is risk-free?"? It seems to suggest that there might be a form of trading in the realm of finance or cryptocurrency that is completely devoid of any risks. However, I'm skeptical of such a claim. Is there really a way to trade without facing any potential losses? Or is this statement perhaps a hyperbolic expression meant to draw attention? Could you clarify and provide more context around this statement? It would be helpful to understand the nuances and subtleties involved in trading, especially when it comes to managing risks effectively.
