I think there is a major problem with bitcoin because a good percentage of its value is due to possible future first time buyers into cryptocurrencies.
The fact that supposedly/certainly many people in the next few months or year will enter the cryptocurrency markets via bitcoin, gives it a pretty good boost in price.
However these future first time buyers will also already have seen many news stories in mass media against bitcoin or about bitcoin crashes (30%,40%). And this is probably going to keep many of them out, even if it's not a reasonable or valid criteria.
Moreover, 2017 was the year of entrance for hundreds of thousands of low buying power speculators and people that were chasing for casino-like gains. Therefore, I believe future investors will be more cautions, more informed and have better alternatives to bitcoin like never before.
