I have no substantial evidence, but I have a hunch that Bitcoin price will remain at the same level as it is now with small fluctuations. For one thing, global governments are still trying to come up with ideas to balance regulation and innovation, meaning uncertainties; for another thing, neither Lightning Network nor Bitcoin Cash see any massive deployment soon, meaning lack of boost power. That being said, any prediction and analysis on cryptocurrencies is probably useless, because it never worked.
