It depends on the level of growth and the time it needs to establish and maintain it in a way we can have it last a very long time. We can't ignore the speculative aspect of Bitcoin, but below all that speculation hides a consistent level of growth that we managed to stretch out till where we are today. I always look at the price and at least cut off 25% of it during normal market activity to determine what a fair reflection of the price looks like. The lowest point I did it at was $7000 and if we deduct 25% of that price we see $5250 pop up, which I believe is a fair price. It doesn't mean much technically, but it did help me not take every latest exchange rate too seriously.
