Bitcoin will always rise because its supply is really low, apart that this started with the cryptocurrency and at some point billions will enter this market and all good projects will go to the moon.
More than bitcoin rising it will stabilize. Thing is, all fiats are devalued intentionally, while bitcoin will find its price and stay there more or less like gold does.
But if you compare it against those fiats that keep getting inflation every year, then it might look like bitcoin will always be on the rise. Its actually everyone else going down, and that's not bitcoin's fault.
You see, the USD has to lose 2% yearly because that's the the Chicago school dogma dictates, and so do most of the other fiats, more or less, they always have to lose value. They are scared of deflation, something the Austrian school explains pretty well how can the economy work with.
Follow the Austrian principles and everything falls in place. Keep thinking the other way, and you will always be scared of a coin that doesn't lose value over time. For starters, put an end to fractional reserve banking. No more economy growing overnight due to debt, but slow and steady growing due to people's own real savings.
