As long as there is debate on the technology, I think it's fine. But if it's all "BUY YOU'LL GET 100X, LAMBO MOON!!", then yeah, I agree.
If it's that, just try to deviate the discussion on the tech, that is far more interesting

I think it's more "do your research, and then invest or don't"  

In my case, after my own research, I invested.
