Before signing up here, I was skeptical about the credibility of this website, reason being that I have come across some other websites as well that have bitcoin in their names like "bitcointalk", but all they do is advice you to invest with them.
This is already bitcointalk. And while the name suggests that this forum is all about Bitcoin, it actually is not. Surely you can talk about Bitcoin in all its aspects here, but you are also allowed to discuss about altcoins, gambling, economics, politics and society, and even off-topics. There is even a marketplace here and a currency exchange section.
I’m a bit surprised that you’ve been in crypto for a while and you’ve already encountered a number of sites dedicated to it but it’s only now that you’ve discovered this forum. This is the oldest forum dedicated to Bitcoin, and which Satoshi Nakamoto himself/herself/themselves founded.
Anyway, welcome to the forum! Explore and enjoy!
