I can see bitcoin keeping a strong price for a long time to come. It is still very early in it's adoption and has only recently had an explosion of interest and investment which has made the price rise so high. A lot of people are still coming to grips with what it means and how they can use it. I expect this interest to continue and the price to rise before stabilising. The threat to its price could be other coins or tokens coming into the market like eth, but it is a very exciting time at the moment as there is a definite shift in how and what we call investments.
