If I have to judge with the past crypto history its always something new every bull season, who would have thought that meme coins will cause a stir in crypto space last bull season? Maybe in 2024 we will yet notice another use case again?...
I think it's only a coincidence that on each bull run, there is also a new trend in the space. Can't say new addition since some can just disappear and became obsolete (ico for example). It came once with a bang on the year 2017 when cryptos are experiencing their new ath but a year or so later, ico have fallen and replaced by ieo, ido, and others.
Bull run can sometimes take a long time to occur like 4 years, so with that long, new discoveries are likely going to come. Meme coins came in I think after ico trend but unlike ico, meme coins are useless. They don't have use cases. Even without new trends, bull run can still come on their own.
