There is no relationship between bitcoin price and visitors on coinmarketcap or even bitcointalk forum, these are simply updates channel and discussion channel respectively.
While I've noticed the drastic reduction in active users here in the forum, I wouldn't actually call it a disadvantage, we could hence have some good discussions as well as reduce or do away with those who want to get rich immediately
put a statistic over both and we can discuss this claim.
there is 100% a correlation
and i am afraid that this forum indicates the future.
because there was first this forum and then there was a bitcoin price.
