Unfortunately, volatility is still a feature of these currencies, therefore it attracts speculators and those who believe in their long-term value more than ordinary traders.
Volatility is something that need to be addressed if we want to have a living on bitcoin. Within days bitcoin can have a jump of over 1000 USD. If we dont have stable BTC price we will continue to have BTC that will be only an asset of storage.
How do you control or address volatility? Kill all the whales and confiscate their hodlings? Of course, that isn't going to happen. Besides, volatility is what makes Bitcoin popular and what it is. Some of us need that volatility to excite trades. Without it the market seemingly stays down.
The volatility in this market is never going to be controlled, as you say the nature of this market will never allow that and lets be honest many of us do not want that, I like the volatility of the market and the fact I can make a lot of money with it in a short amount of time.
This means that people will have to adapt to a currency like that and while this may seem discouraging as fiat is way more stable I think this is going to change once we see another financial crisis and fiat shows that it can be volatile as well except that fiat always losses value while bitcoin has a tendency to go up.
