I don't think the era of shit coins will ever end as time goes by, they will increase. They will be used in different things which may become our need, Apart from this, those who do rug and pull will also need them and it is also important for those who are thinking of becoming a millionaire in the short term.
I don't think shitcoin could ever become our needs, it's different, like meme coins, it's indeed interesting how they could survive even the luna crash and retain their value but at the end of the day, they aren't becoming our needs, instead they now rather stuck, since they are like last alternative when it comes to investing, the first ones are still the ones that have real utility, like eth and bnb, shitcoins just gonna become shitcoins, nothing more.
