It was another wild week for bitcoin. From price swings to the CFTC to the SEC and all the way to Davos, here's what you can't miss this Friday, Jan. 19.

Crypto Trader Gets Caught

The U.S. Commodity Futures Commission announced that it is charging Patrick K. McDonnell and his company CabbageTech with "fraud and misappropriation in connection with purchases and trading of Bitcoin and Litecoin." The Staten Island, NY-based outfit had promised customers real-time trading advice, which it never provided before it essentially disappeared after receiving payment. The commission wants to return funds to defrauded customers.

SEC Nixes Crypto ETFs

The Securities and Exchange Commission said that there are too many questions surrounding cryptocurrencies for it to sign off on exchange-traded funds for bitcoin and other cryptocurrencies.

"Recently, the growth in cryptocurrencies and cryptocurrency-related products has attracted significant attention, and we have seen interest among sponsors in offering registered funds that would hold these new digital products," the SEC's letter read. "[We stand] ready to engage in dialogue with sponsors regarding the potential development of these funds. We believe, however, that there are a number of significant investor protection issues that need to be examined before sponsors begin offering these funds to retail investors."

Cryptos Star in Davos

As TheStreet's Annie Palmer writes, cryptocurrencies and blockchain will be the stars of the show at this year's World Economic Forum in Davos, Switzerland. The Davos lineup features a number of panels on bitcoin, crypto and blockchain - they could offer some much-needed legitimacy to the virtual currency space. Big names talking bitcoin when the Forum begins Jan. 23 are Treasury Secretary Steven Mnuchin and IMF leader Christine Lagarde.

This Week in Prices

It was a tough week for bitcoin as the $20,000 range remained prominently out of reach. According to CoinMarketCap, bitcoin finished Monday trading at $13,819.80, finished Tuesday at $11,490.50, Wednesday at $11,188.60 and Thursday at $11,474.90. In afternoon trading Friday, bitcoin was lower more than 3.5%. Ethereum and Ripple were also down for the week.
