Goldman Sachs, a leading global investment banking, securities and management firm providing a wide range of financial services to a substantial and diversified client base, is rumored to be considering the launching of the direct Bitcoin trading service.  

As detailed by wsj.com, Goldman Sachs would open a whole new marketplace for investors.

In response to client interest in digital currencies we are exploring how best to serve them in this space.

Letting alone the client interest, Goldman Sachs also looks to benefit from the inherent volatility present within the cryptocurrency markets: the traditional markets have been less volatile lately, so the investment banks like Goldman have posted sluggish revenues from their trading operations. As cryptocoinsnews.com speculates, though the dramatic price swings within the crypto markets intimidate many investors, professional traders view this volatility as an opportunity to reap significant gains.

Chinese Miners to Fall Victims of Ransomware

In China, a ransomware spreads, victims of which are Bitcoin miners. The damage from its activities is measured in tens of thousands of dollars. This is reported by Trustnodes.

The virus infects miners, released by Bitmain, and requires you to send 10 bitcoins, otherwise threatening to cause overheating of the device.

The problem is solved by formatting the SD card of the infected device, however, as Trustnodes notes, the whole process can take up to four days, while malicious software rapidly spreads to the other miners.

Probably, the virus comes with an "improved" firmware for miners. Some owners install such firmware to “overclock” their ASIC devices and improve their performance.

The first messages about the virus refer to August last year. In particular, Antminer S9, T9 and even L3 + for Litecoin were attacked. Over time, the malware has been improved. Now its distributor himself can decide when to display a message requesting a ransom. One miner also said that one night the address to which the 4,000 devices belonging to him sent the mined cryptocurrency was changed to the address of the hacker, which brought him $ 8,000.
