It is very hard to predict with certainty which coin will go 1000X in the next bull run, however, I think AI (Artificial intelligence) based coins have the potential to outperform due to rapid ongoing development & advancement in this technology. We have witnessed huge interest in ChatGPT since it was launched, which is evident from huge traffic on this site and it has got millions of subscribers within days, who are regularly using it to get useful information.
AI-based projects are really popular right now, I also followed suit and started doing research on several projects that run on AI platforms. As you explained about ChatGPT which has started to become a concern lately. ChatGPT an AI platform that will provide any knowledge very easily.
AI projects may be able to reach 1000x but we still can't research which projects will eventually be in demand and achieve a tremendous increase.
