People are still exited from last years rise, and now people believe that bitcoin price will grow every year with same speed, that can happen or not. Maybe we will have a calm year with steady grow, maybe we will recover this previous ATH and big things can come in next year. Its possible for price to get to 50000 dollars, and eventually we will see that mark, when will it happen nobody knows.
If we recover previous ATH in some near future bitcoin can easily get to 30000 dollars, but last year was too good, I believe that we will need to wait year or two to see one more great year, so don't have high hopes for high price to come fast, give it a time, maybe we will stay where we are know for a while, that isn't bad at all in my opinion, people will have time to accumulate more bitcoin at this price.
