How to know when to HODL vs when to sell?

Im always stuck between HODLING and just straight up facing reality. I invested $2000 in to the first ever AI meme coin yesterday, and wake up to $1300. A lot of the advice on Crypto Twitter is to find a coin that you think has good chances and then just HODL and have conviction but I also see people saying be smart and know when to take your L. How the hell do you differentiate the two. I know tiktok normie memes are taking the spotlight right now. Even most of crypto twitter is now busy chasing the latest tiktok normie meme hoping to catch a quick pump, but are AI coins completely done for now? The good news is that bitcoin is soaring. I want to hold but Im not sure if this whole AI thing is going to even maintain popularity. Can somebody give me some advice pls 🙏
