Short-term price volatility should not have a significant impact on the holder's long-term plans. In fact, I believe that holders are very likely to accumulate when the price drop a few percent at a time, which will clearly give them the opportunity to own more bitcoin before the price rises high. Halving can certainly help increase demand for bitcoin indirectly, but this takes a lot of time.
What you've just explained is clearly based on a logical value. I see no business between a long-term investor and volatility. My reason is because, long term investors are indirectly not affected by any current fall in price, as there is still a very big chance of price increase and even great profit as more demands and time goes bye.
Unlike a short-term investor that needs to stay updated with everything especially paying more attention to volatility, rumors and speculations. Failure to stay updated might cost the short-term investor alot as things can happen just in a blink of an eye.
