Bitcointalk played a major roles in projects in the previous years especially when token sales and ICOs were a thing. Then, only a handful of people would invest in your project even if you had a Google or Facebook ad campaigns running for months. It's only when you combine the traffic and investors on bitcointalk that it gets the much needed traction. These days, it has changed. There are platforms dedicated to market token sales and there's an high influx of investors who don't necessarily need to see it on bitcointalk to take part.

Now, I only see speculation threads about how these new projects. I guess that's how it'd be unless things changes.
