In our field if you can make long term predictions then you wouldn't call it volatile really, because you can predict what it is going to do exactly from a couple to a year up front sometimes even years up front. It only looks volatile to people who aren't sure what they are doing.
Bitcoin price is very volatile and it is true for all, not only for traders but also true for long-term investors.
I don't know how you can make market predictions in next couple of years or longer time accurately. You must be too confident by saying lime this while predictions basically are hard to make accurately for all markets, not only Bitcoin market.
You can be a long-term investor, know what you have been doing and your belief in Bitcoin comes from your due diligent research and deep knowledge about it and the market cycle history, it won't change a fact of how volatile Bitcoin price is over time. It won't change a fact of uncertainty in Bitcoin and its unpredictable price in future.
