It will need to become more stable, certainly, but I think that's a function of how the market interacts with it. If the majority of Nano is being priced based on speculation through exchanges, it will continue to have this kind of volatility. But if money continues to enter the system via other use-cases, aka its actual utility, volatility will diminish. Pricing becomes less about speculating on it as an asset and more about utility as a means of transaction.

The reason you don't see this with other cryptos, by the way, is that their utility is severely limited (in a technical sense) and therefore the underlying value is entirely speculative.
