Is bitcoin volatility here to stay and not decrease?
Don't shoot the messenger, okay?
As I have a really bad message for you. Volatility is not just here to stay, it is likely to increase if we expect the prices to rise in the future (with adoption rates negligible). Bitcoin has limited supply which can't possibly be increased following the rise in prices (as is the case with gold, for example). Higher prices bring more volatility, and that seems to be a kind of dead end for Bitcoin. This phenomenon is real as proven in late 2017 and being proved again now
All in all, it means that at higher prices the market supply will reveal a tendency to decrease, which will lead to higher levels of volatility (contrary to popular belief). In fact, this is exactly what we see with prices above 10k right now. There is neither supply nor demand in sufficient amounts but a lot of space for volatility instead, which will only expand further at higher prices in the lack of real adoption (which could wind it down a little)
