where you keep your winnings on your front porch.

Volatility, for starters. Its 52-week high and low produced a difference of $800, with many sharp peaks and deep valleys in between. And bitcoin, like any kind of money, only has value if everyone accepts that it has value. If another, more refined digital currency comes along with a “killer app” that makes it supremely user-friendly, users might sell off and abandon Bitcoin, driving the price into the ground.
