If such people hold in spot said alts - they can wait all they want till the alt season hits eventually, in my opinion.
No need to be shakin' off your bags 
Right now, many investors are very worried about the chances of an altseason this cycle, because the ETH price is still low and we haven't seen signs of a major trend in the crypto market. I'm not sure all altcoins holders can hold until the next season, if an altseason doesn't happen this year, I think most will panic-sell their altcoins at the harshest point of the 2026 crypto winter.
Personally, I also plan to sell my altcoins in 2025 instead of holding until the next season. I'm still hoping an altseason will happen in the next few months, creating an opportunity to take profits before the uptrend ends. In a worst-case scenario, I'll cut my losses on altcoins to have money to DCA next year.
