Didn't check for the whole thread, guess it might've been said, but mass adoption and lack of transparency on top of regulation attempts is what can be considered a hindering factor for the crypto market.

ICOs booming in 2017 and kinda dieing in 2018 is a thing of a past already, however, that brought us to a current state of skepticism and uncertainty.

So, facebook coin, JPM coin and etc. hopefully will solve these problems, but who knows what it'd look like.
