You need your head examined if you believe this forum has any effect on the price.
People who are bearish and don't believe in bitcoin, when price is declining have confirmation that their beliefs are right,
and there is nothing better than knowing you're right and rubbing it in people's faces.
there is even a study that says social media like bct is affecting the price of bitcoin.
and to be honest, bitcoins price is what people believe it is (atleast for now and in the short/mid term).
so its pretty logical that the price would be affected by social media.
