A number of important developments arrived for Bitcoin and cryptocurrency over the past week. Among the biggest stories were Yahoo Finance adding three cryptocurrencies on their iOS mobile app and a mention of Bitcoin on the surprise Eminem album that released this past Friday. There was also an update from the NSAA's investigations into crypto investments as well as news about North Korea's crypto efforts. It was reported this past week that Yahoo Finance has now added Bitcoin (BTC), Ethereum (ETH), and Litecoin (LTC) integration as part of the iOS app. Yahoo released a press release indicating that users will be able to trade crypto on Yahoo Finance through the use of TradeIt, a third party service. This gave a boost to the credibility of cryptocurrency as it is being embraced by the financial world. In another win for cryptocurrency, JP Morgan Chief Information Officer Lori Beer commented this past week that he believes blockchain technology is going to ultimately take the place of the current technologies. Beer said he estimates this will happen over the "next few years." He indicated JP Morgan uses the blockchain technology to help store customer information as it relates to "Know Your Customer" or KYC. In addition, he said it simplifies the payment process and that JP Morgan specialists are "evaluating what is happening" with it all. A report came out this past week that North Korea (DPRK) tried to mine Bitcoin "on a small scale." The mining took place in a time period spanning May through July 2017, but was reportedly "unsuccessful." It was also mentioned that Chosun Expo, a North Korean technology firm is trying to develop their own Bitcoin-based cryptocurrency exchange. Both reports originated from the Korea Development Bank (KDB) from South Korea. Also this past week, North American Securities Administrators Association or "NASAA" gave their latest "Operation Cryptosweep" details. They said there have been over 200 investigations so far in terms of Initial Coin Offerings (ICOs) and other cryptocurrency investments. NASAA continues to recommend that investors perform "due diligence" before making any cryptocurrency investment decisions. In addition, they indicated that if a project is considered a security it should be registered appropriately with a regulatory agency. If they haven't done that, it's necessary to file an application for exemption from having to register. References to Bitcoin or cryptocurrency are also popping up in a variety of places. On Friday (Aug. 31), hip-hop star Eminem dropped a new surprise album called "Kamikaze." On one song called "Not Alike," a guest verse from Royce da 5'9 includes a shout out to Bitcoin. Royce raps, "everybody used to bite Nickel, now everybody doing Bitcoin," showing that the cryptocurrency is gaining ground even in popular music. It's also not the first time it's been mentioned by Royce da 5'9. The rapper previously included the line "Discussing bitcoin and cryptocurrency" on the song "Era" from the album "Prhyme 2."
