Well people criticize and hate what they don't know in the beginning and with time when it comes  stable they just adapt to it, that's how it is through the history. But even with that there are still skeptic people and no matter how much they see proof of something stable they'll never change. so those people gonna keep hating.

But yeah, for smart investors who embrace Crypto currency and those who will get into in "better late than never" situation will still win. and like you said in the post , Bitcoin, not only BTC, but Crypto currency will silence it's haters and disbelievers with time.
