Not necessarily mate, there are coins that do well in one bear run only to recover a little in the next bull run and then get abandoned in the next bear run, because the developers become tired of the constant "crypto winters". Most altcoins are anyway going to be like that because this sector is niche and has a very small group to market on. Such altcoins will only come to make money for their own advisors and teams but then run away before you know it.

While mainstream markets survive bear runs because of a lot of supporters out there and because they already have a working product/service, such solid evidence is lacking in crypto where many vaporware projects run like anything.
