The wild fluctuations seen recently are a result of this currency being so new, and in many cases being owned in large chunks by a few people who decided to sell out and grab a huge payout. The price will stabilize once more people have more pieces of the pie - once it has "ripened" a bit. In a way, these people selling their huge amounts of btc is a good thing, as it will then be distributed to a greater number of people.

Also we should see more stability as more products and services are available and bight and sold.

Until then, enjoy the ride!
