While U.S. equities markets tank, and gold is hanging near a one-month high, one famously volatile currency is roughly flat on the week.

Bitcoin, which made news when it dipped to an 11-month low earlier in October, is up about 1.6 percent since Monday morning, according to CoinDesk's price index. While this may be a big move for some currencies, the relatively illiquid cryptocurrency routinely sees $20 swings in a day: It has moved from about $371 to roughly $377 since Monday.

In fact, the digital currency's volatility is still near all-time lows despite the major changes experience by other markets this week, according to the Bitcoin Volatility Index.
