Since there is a limited amount of bitcoins i think it's bound to happen that it will rise to a crazy amount we cannot imagine right now or believe in it. Every new offline shop or store that accepts bitcoin as a payment is a step forward.
And with every milestone we reach as like 5000$/1BTC bitcoin itself will get more and more exposure from different type of media which attracts a lot of people that didn't hear from bitcoin before or thought it was just a "hype" that dies down soon or even just a big scam.
I think it's good to "think big" but we shouldn't expect that it keeps on rising like it did the last couple days.
