How long can you survive if the Bear keeps going?

I've seen posts about people giving up on their crypto positions in multiple crypto subs and other social medias recently.(maybe bottom was in huh?) I know there are people with diamond hands who hodled from the very start and are still going very strong. I don't want to ask them. I want to ask the ones who entered the crypto scene after 2021 November ATH.

How long do you think can withstand the winter without any profit from your portfolio before you get tired mentally and financially if the bear keeps continuing, 1 year, 5 years or 20 years?

And what are the things that you think to keep motivated?
