While I also think that monitoring social trends is good, especially when one is seeking information, market trends should also be explored in the same time. I second, @noorman0, there are indeed distinctions on how social and market trends are approached in the collection and analyzation of their respective statistics. Nonetheless, considering trend under both sections could indeed provide reliable information about bitcoin and the crypto industry.
It's good to have it somewhere in your mind but I don't think it's something you should rely on. Also, it depends on source and interpretation. Social trends are to my opinion only the one component tightly related to economic one when we speak about Bitcoin trends but also very dinamic and prone to change so when it's analyzed a certain amount of caution is needed.
Yes caution is needed but I think there is for sure a connection between market price and people behaviours. I guess we just need to understand the right key to read that.
