It is like this, it means Bitcoin has been going more nearly to main stream, and it's good for Bitcoin. The Bitcoin forum, if so, is already completed its most important mission, bringing Bitcoin to more people, to the world, and expand Bitcoin adoption.

If from now, Bitcoin can grow up more without this forum, is it good, isn't it?

I don't imagine that Bitcoin forum will die or disappear but with fast growth of blockchain and cryptocurrency industry, this forum will be covered by many altcoin forums. I don't say those forums are bigger, more important than Bitcoin forum, in fact they are not, but Bitcoin forum will still be valuable with many people in cryptocurrency industry especially Bitcoiners and Bitcoin maximalists.
