New technology is upending everything in finance, from saving to trading to making payments.

Bitcoin’s price surged today amid mayhem on the larger exchanges where the digital asset is traded. Prices quoted were sometimes a thousand dollars or more apart as the platforms reported their systems weren’t operating properly.

Bitfinex, one of the biggest exchanges, said it was investigating a denial-of-service attack, while Coinbase said its GDAX platform had a “minor service outage.” Gemini said bitcoin deposits were temporarily unavailable.

Bitcoin was quoted at least at high as $18,500 on Coinbase’s GDAX before falling as low as $15,101. The cryptocurrency was trading at about $14,000 at the start of the day, according to CoinDesk. It started the year at around $1,000.

A spokesman for Coinbase said price movements as high as 20% within a few hours aren’t uncommon for digital currencies, and that price fluctuations on other exchanges were similar in magnitude.

The homegrown technology used by many cryptocurrency exchanges is coming under strain just as big Wall Street firms will soon have much greater access to bitcoin. Institutional investors generally haven’t been able to trade this new breed of digital assets because they could run afoul of regulations. Futures, which allow traders to speculate on the future price of an asset without actually owning it, solve that problem.

It will be easier for major players to buy and sell the derivatives provided by global exchanges in Chicago, because they already trade other instruments—tied to stocks, bonds, commodities, and the like—on those regulated markets. Last week, the US Commodity Futures Trading Commission cleared the way for three firms to launch bitcoin derivatives.

Exchange operator Cboe Holdings will launch its bitcoin futures contract this weekend, while CME Group says its futures will launch on Dec. 18. These exchanges will rely on prices from the likes of Gemini and Coinbase for their derivatives contracts.

The Futures Industry Association, the main industry lobby group, warned that the introduction of bitcoin futures “did not allow for proper public transparency and input,” according to the Financial Times (paywall). While many in the industry see a chance to make money, others are concerned that the huge volatility in the market is dangerous.
