There are lots of people against crypto than for it. That said, it means the people for it have been dwarfed in comparison to those against it. Added to that is the effect of media and the government at large. Their actions have not encouraged newcomers to come in, rather chasing them off as cryptocurrency is either deem a Ponzi scheme or a failing prospect. If those two agents above have a changed orientation about cryptocurrency, people joining it won't be hard. Add the issue of price to it, and you will have another thing scaring people off.
