I'll give you one advice: Never go behind trends because trends fade away, especially if you are planning to invest and not trade because when you invest, you tend to buy and hold for the long term, and in that time, the trend might be gone already when the time comes for you to sell. That's why you always focus on projects that aren't trend-based and AI projects are based on a trend and this trend will fade away over time.
However, if someone is trading, which means they are buying and selling in the short run, they can surely go for projects that are currently trending because such projects will have higher volatility and that will provide the trader with more profit opportunities and that is a positive thing in trading if someone understands.
