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. (Yes technically by literal definition it is and has been but who cares about technicalities). You could entirely very safely predict that when regulations would go through BTC will go into chaos while ETH would draw power from it just because why they are both used. (BTC would only stand if they make it something more).
