well, get used to it because the market is not going to stabilize for many years and things will be more or less the same until exchanges become a lot bigger than this or we reach mass adoption.
the good news is that the volatility is decreasing compared to previous years. so the growth is happening but it is not yet enough to prevent manipulation and the resulting big drops.
there is no any currency that can be stable, all are always moving to make changes, things like this are also experienced by bitcoin, the price of bitcoin certainly cannot be stable as long as there is support and rejection, all over the world, so long as all countries have not agreed on the legality of bitcoin during that time will also often occur price movements, but we must be sure that sooner or later bitcoin will become the single currency in the future.
