Investing in cryptocurrency shouldn't be too risky if we are really serious about mass adoption. The Stories about people losing their minds as a result of crash should get us thinking. Crypto should not be allowed to degenerate into a system it is trying to resist.
Every Cryptocurrency should have a stable version of itself people can switch to when they want. The best thing about the Stable version is that it will still increase the value of its main version when bought by investors. Example: Bitcoin goes up in price when someone buys a million dollar worth of Bitcoin.S ( Stable Bitcoin). Someone said this could be done with Sidechain but it would be difficult. Am sure you know what Sidechain means by now.
I think this will help keep crycurrency from dangerous crashes.
I have do disagree with your statement,cryptocurrencies will never be stable for as long it is not regulated which is not an option because these currencies are created to counter any regulations by the government,someone needs to control it before the price would be stable like fiats.
