Probably the first thing you'll notice if you've been following cryptocurrencies is that they're exceptionally volatile. This derives from the fact that virtual currency trading occurs on various cryptocurrency exchanges rather than a central exchange, leading to increased volatility.
Since the year began, the aggregate market cap of all cryptocurrencies combined has increased by more than 3,200% as of Dec. 18. Nonetheless, bitcoin, the world's most popular cryptocurrency, has undergone four corrections of at least 20% over the past six months. In short, cryptocurrencies aren't for the faint of heart.
