I don't think so, because there are many factors that can affect the price, so the price becomes volatile and unpredictable. like a year ago it fell at an unexpected rate after the price reached 20k
Bitcoin will never become a stable coin. Based on supply and demand law bitcoin price should be tend to rise. The limitation on bitcoin maximum amount and the growung number of people who want to obtain bitcoin will make its price increase. Bitcoin is not spread evenly yet, I mean there some people who have a lot of bitcoin they can make its price move extreemely.
bitcoin should indeed become a rising coin, but nowadays bitcoin sometimes experiences pumps and dumps. so I think bitcoin can't be said to be a stable coin, but bitcoin is far better than any coin at the moment.
No one can predict even though currently bitcoin can be said to be stable.
but I personally bitcoin is more efficient to invest in the long term, to avoid worries or doubts and stay consistent to wait for the highest price, it would be much better if you feel doubtful in the movement of bitcoin.
