Bitcoin can't controlled with any sector, it's decentralized. We see that the price is going pump and dump. They says many people know the value of this bitcoin with volatility price.
Yeah I know the decentralized bitcoin. but what about users who have very large capital and much bitcoin in their bankroll. and you know that bitcoin users are very easy to panic with speculation and issues. maybe my opinion fluctuations could have been in control but the result does not guarantee according to their expectations
So there isn't how to control volatility, we must deal with this on Crypto-Currency world, it's the nature of a decentralized currency and I think it's good as it is. Who are unable to take the risk can use centralized currencies, the stable ones, and at same time, unprofitable ones. People complain about volatility, but complain about stable currencies too (fiat)... However, there are few AltCoins that follow fiat price, so they are very stable.
