Bitcoin does not have counterparty risk. Your coins remain yours regardless of who else was doing risky bets and went bankrupt. (Provided you hold your own keys.)

As for volatility, that's purely a function of holding distribution and market liquidity (and the market right now is far from saturated - hence 30% dips and huge potential upside in the future). As soon as the "whales" are thinly spread across the globe, you don't have a risk of your coins' value suddenly crash because of one guy selling his holdings.
