Do stability exist? Can a currency realize stabilize?

Even EURUSD pair is quite crazy sometimes.

Even BTC stabilize, USD will never be stable. Crazy events in the world will make the price go up and down.

The life of btc holders will always have huge up and downs. Volatility will become smaller, but we will see at least some 20% up and down in a year for sure, just like gold and other assets and currencies.
