We tend to mix up different things. Bitcoin is pure math in a way. And yet it doesn't mean that it's price can be mathematically predicted for real. Because our world is not math. Everything is changing here and you never now whether you will still be where you are in the future. So, we shouldn't think that Bitcoin will really be 1000 in June. A lot of things can happen till then.
Bitcoin is an unpredictable job and nothing can be said about it and the reality is that we may even see that price by the end of the year as everything will depend on the user adoption and if everything goes smooth from here then we don't have to wait longer to see the price of $1k.
