In my ether wallet I have more than 30 coin that are shit and I got the coin from bounty and airdrop campaigns. The main reason why I hold this coin is because basically I got them from free participation and holding them won't take anything out of my wallet just that whenever I open my wallet I would be pissed off sometimes checking how useless these coins are.
LOL, you don't have to say anything about shitcoin because it's just a decoration that you'll only see until you really want to get it out of your wallet or replace your wallet. I had 2 shitcoin from the bounty when I first joined the forum, it was completely useless and I just threw it away without having to look at it now.
If there are people that are still buying and trading the shitcoins on exchanges then altcoin season will definitely make such coins bounce or pump just like what happened in 2017 but if there is no buy order it won't do any good even if price bounce a bit, I've seen those who are accumulating shitcoins for altcoin season
In general, shitcoin are non-tradable asset because no exchange is willing to host them, so why would they collect them? I think these are very low value altcoin and are still trading, but don't be swayed by such altcoin because you might get stuck with them.
