Bitcointalk.org only gets nowadays 3.1 million viewers thats actually nothing compared with it once had per month (over 30 milion)
during the 2017 bubble?
you can see the same sort of decline in google trends data for "bitcoin":
it's reflective of the overall post-bubble decline in interest in bitcoin. be patient---it took a long time for the market to get hyped again after the 2015 bottom. there's no reason the 2018 bottom would be any different.
