If there is another forum like Bitcointalk, nope, you wouldn’t find any forum like Bitcointalk. This forum remains the one place where you would find like minds as well as those that are out to spread FUD but, don’t always get to do that successfully as many here knows better.

Contents here are more authentic given how the forum doesn’t take kindly with plagiarism and you find a lot of authenticity in what is discussed here.
Users here are very enthusiastic and really active as compared to anywhere else.

If there are other crypto forums,
Yea and one of those is Altcointalk, it does its bit but, not as much like we have here.
