Despite decreasing in value, BTC is far from getting over. The technology behind it is evolving in "silent", transaction fees are getting lower, speed is much faster. However, due to broader usage of blockchain technology, and because of it's nature, BC might seem more popular right now. Banks, governments, corporations are implementing BC in its processes and for that, they don't specifically need BTC. But BTC supply is limited, there is demand and at least in a future might be a collectible thing to have (if not anything else but I highly doubt about that). But I am sure it will be more than that.
