Majority of Bitcoin's value comes from speculation rather than fundamentals (scarcity and utility), we can see it by how much the price moves without any change in fundamentals at all. And it makes Bitcoin really unpredictable, it's almost impossible to make any educated guess for where the price is going, maybe we'll see $100,000 or maybe $100, maybe even both - who knows.
We can expect both the value to increase and the number of users to increase exponentially so long as the current technology maintains itself and remains both useful and in a limited abundance.
Why? People so often make these "moon" predictions without any proof that the growth will indeed be exponential. Drawing parallels with adoption of other technologies doesn't actually prove that Bitcoin will repeat their history.
