It will take some while for a new bull run. That is unless there is a major outside event. And there are a couple of possibilities.

Brexit might cause people parking their pounds in bitcoin to minimize the risk of holding pounds. The more uncertainty in the UK the better for us. But I dont think brexit will be that dramatic so I dont expect much.

On the other hand if france or italy destroy the euro, that could cause a major uptrend for crypto. Lots of people in Europe will try to get rid of their euros when there is bad news and crypto is the logical path to do so.

While I think that 2019 will be quite boring crypto year, there are in fact some events that could trigger a bull run.
