I love crypto and the possibilities of it. The issue I have is that there are really no killer mainstream apps. Most people I know have heard of it but still have no clue how to get it. To this day it remains a struggle with limits and wait time and for something to be disruptive to the financial industry, it can't be slower with more regulations.
SteemIt in my opinion, could be that killer app. What's more mainstream than Reddit and SteemIt takes into Reddit but with the added crypto touch. Consider me a believer.
