But we need to understand that the structure of Cryptocurrency is decentralized and that could be the reason the volatility.
To solve the issue of volatility, then there is the need to change the structure from decentralized to centralized which in itself is not feasible.
I don't think that changing the structure from decentralized to centralized can solve the volatility issues... and by the way, Bitcoin, for example, is born decentralized and cannot turn to a centralized system.
In my opinion, volatility will decrease while the crypto market becomes more mature and bigger. We are still talking of a very young market.
