There's a natural monopoly in a medium of savings used to defer consumption. Among competing currencies, the winner is the "bubble that doesn't pop". Until the monopoly is established, though, volatility is to be expected, as it would be with any bubble.

I watched this for three minutes and in that time its value went from 37 to nearly 40 and back to 37 again. Several times.
