I think most of us are wrong the hopes of bullrun this year is getting slim, it seems that this is the year of capitulation which very opposite from last year some predicts that it could go lower. But 2019 might be a different year for crypto hopefully more positivity and adoption.
As I understand it, we can say that the bulls have entered the market when we see all cryptocurrencies (at least, the tokens from the top-100) have gained and added at least 20-30%. Suppose, it will happen this winter.
