It can easily be triggered by those factors I've mentioned. There are people who keeps on making money from these campaigns. As long as there is/are reasons for its existence then it will be there. However if it is with which memecoin could be on top of this narrative, then it would be hard to tell. On a daily basis, there are many meme projects being introduced across different exchangers and any of those could replace on the other hand. These coins are already a part of this growing industry. No development is expected with most of these coins but if it is just with market existence the every coin has it.
