When will we reach the state of more of less stable cryptocurrencies or it is in their nature and will never end?
Volatility is bitcoins characteristic so dont expect that it will become stable. Actually, its its advantage that it is volatile because it maximizes the chance of income and profit because when the market is down, you will be able yo buy bitcoin cheap then when it goes up, you can sell it more expensive. I think it will remain and will always be unstable and let us be thankful about it.
