I think you're wrong by several orders of magnitude in one direction or the other. i.e. $50,000 or $5.
It will never crash for obivous reasons, but 50K seems too far fetched on that limited amount of time. My take is that by about 2025 we'll be at around 10 times the ATH (12K)
consider that by that time(2020) only 1-2 million coins will be left, so the price must increase by an enormous amount, it's not linear for sure, it's exponential
