2. -- Goldman Sachs to Name New Trading Co-Head

Goldman Sachs Group Inc. ( GS) plans to appoint Jim Esposito as the new global co-head of its trading arm, The Wall Street Journal reported.

Esposito will run the securities division, one of the largest on Wall Street, alongside current executive Ashok Varadhan, the Journal reported, citing people familiar with the matter.

Varadhan has been a co-head of the unit since 2014, but his status has been unclear since his two co-heads resigned in June and weren't replaced, unusual for a firm where multiple executives typically share power, the Journal noted.

The division has struggled, bringing in revenue of $12 billion last year, down from a peak of $33 billion in 2009.

4. -- No, Starbucks Isn't Accepting Bitcoin

Customers at Starbucks Corp. (SBUX) won't be able to pay for their Frappuccinos with bitcoin despite stories over the weekend about the coffee chain's involvement in a blockchain project.

On Friday, Aug. 3, Starbucks announced a partnership with Intercontinental Exchange Inc., one the world's largest cryptocurrency exchange operators, and Microsoft Corp. (MSFT) . The exchange recently created a venture called Bakkt that aims to integrate cryptocurrencies into global commerce.

Starbucks doesn't want bitcoins, however, but it's willing to help people spend them, according to Motherboard. The venture is an exchange that will allow people to convert their cryptocurrency into U.S. dollars, which they can then spend at Starbucks locations. 

"It is important to clarify that we are not accepting digital assets at Starbucks. Rather the exchange will convert digital assets like Bitcoin into U.S. dollars, which can be used at Starbucks," a Starbucks spokesperson told Motherboard. "At the current time, we are announcing the launch of trading and conversion of bitcoin. However, we will continue to talk with customers and regulators as the space evolves."

5. -- Linde Says FTC Demands Threaten Deal With Praxair

Linde AG signaled that divestment demands from the U.S. Federal Trade Commission threatened the completion of its $80 billion merger with industrial gases rival Praxair Inc. (PX) .

The warning came despite previous assertions that the deal was on track and despite the expectation of approval from European Union regulators, following a pledge by Praxair to sell most of its European businesses to Japan's Taiyo Nippon Sanso Corp.

The FTC raised "requirements more onerous than previously expected," Linde said.

The German company posted a reminder of its agreement with Praxair that if regulators demand the disposal of businesses with more than $3.7 billion of sales or $1.1 billion of Ebitda, either party will be free to withdraw without penalty.
