Happy summer, everyone! Bitcoin has entered the new season in a strong position after an astonishing spring rally, and there is at least a lot of potential for further growth. Last week we saw the number one cryptocurrency climb over $9 000 dollars, stirring excitement both for Dragon Ball meme fans and the wider crypto community. After some steep corrections, Bitcoin has held its ground and hovers around $8 000 dollars at the time of writing.\r\n\r\nIn this week\u2019s news we will take a look at the biggest bitcoin owners, or so called whales, and how their behavior might affect the market. Despite owning a percentually large portion of all circulating bitcoins, most whales seem to be \u201chodlers\u201d, meaning they hold on to their coins regardless of price fluctuations.\r\n\r\nIn other news we have North Korean hackers triggered by U.S. sanctions and how Facebook\u2019s demographics may pose challenges for their upcoming cryptocurrency. Additionally, Irish banks using blockchain, endangered Bitcoin wallets and yet another Satoshi-claimant.\r\n\r\n\r\n\r\n\r\n\r\nWhales accumulate cheap bitcoins\r\nLarge bitcoin-owners, commonly referred to as whales, bought nearly half a million bitcoins in the past 9 months, reports the latest issue of technology publication Diar. According to Diar these whales bought bitcoins when they were cheap and now have a payday as the course has risen through the roof.\r\n\r\nDiar\u2019s analysis states that roughly 25% of all bitcoins have been in wallets owned by these whales. Diar defines any wallet with over 1 000 bitcoins as a whale wallet. According to Diar the past 9 months also saw whales increase their possessions, and right now whales are estimated to own up to 26% of all the world\u2019s circulating bitcoins.\r\n\r\nEven though whale wallets contain large amounts of bitcoins, it seems they form no practical threat to the bitcoin ecosystem. Most of the whales are so called \u201chodlers\u201d, meaning they mainly hold on to their coins despite market fluctuations.\r\n\r\nAccording to Diar approximately 50% of all bitcoins have never been transferred anywhere. Thus it strongly seems that at least large bitcoin owners have faith in the course rising higher than it has before.\r\n\r\n\r\n\r\nFacebook\u2019s demographics may hinder Facebook\u2019s own crypto\r\nFacebook\u2019s upcoming cryptocurrency may face problems as Facebook\u2019s users grow older, states a recent publication by Diar. According to Diar Facebook\u2019s average age is starting to be relatively high compared to the average user of the internet and cryptocurrencies.\r\n\r\nOlder people generally have a lesser understanding of cryptocurrencies than younger ones. In case this also applies to Facebook, the older users may have difficulties in adopting the use of cryptocurrencies.\r\n\r\nDiar also estimates that Facebook\u2019s younger users who understand cryptocurrencies may not be wealthy enough to use the cryptocurrency in any significant amounts.\r\n\r\nFacebook intends to publish its project dubbed Globalcoin by 2020. The social media giant has tried to form collaboration with at least the exchanges Coinbase and Gemini.\r\n\r\n\r\n\r\nPopular paper wallet site might be unsafe\r\nHarry Denley, a security researcher from MyCrypto.com, has published new information warning of the paper wallet site WalletGenerator.net. According to Denley, the site is vulnerable to abuse and may give out same private keys to several users.\r\n\r\nDenley studied the original open code of WalletGenerator and compared it to the services of WalletGenerator.net on the internet. According to the analysis, the codes stopped matching each other sometime last August. Denley states that the program creating paper wallets may generate the same private keys for several different users.\r\n\r\nDenley also tested the system last week, but no longer found these anomalies. Despite this researchers find WalletGenerator\u2019s activity to be suspicious and recommend against storing funds in wallets created by the site.\r\n\r\n\r\n\r\nNew Satoshi-claimant found\r\nA new Satoshi Nakamoto has been found \u2013 or at least a guy alleging to be the mythical creator of Bitcoin. According to the U.S. Copyright Office, Wei Liu, a Chinese crypto entrepreneur living in California, has sought copyright for Bitcoin\u2019s original white paper.\r\n\r\nIn his copyright claim Wei Liu asserts that he published the original paper in January 2008 under the pseudonym Satoshi Nakamoto. However, it seems Liu\u2019s claim is more about satirizing previous copyright claims than gaining actual power.\r\n\r\n\u201cI filed it just to let people know anyone can register a copyright. Everyone can be Satoshi Nakamoto,\u201d Liu states.\r\n\r\nWei Liu is so far the second person to have sought copyright for Bitcoin\u2019s publication paper. Before Liu the Australian investor Craig Wright sought copyright by claiming to be Satoshi. Wright has, however, failed to provide evidence of any kind and his claims have generally been met with criticism and laughter by the crypto community.\r\n\r\n\r\n\r\n\r\n\r\nIreland\u2019s biggest banks start using blockchain\r\nThree of the four biggest banks in Ireland have started using blockchain technology to keep track of their employees\u2019 competence and ensure that employees meet the requirements of Irish law. The Bank of Ireland, AIB and Ulster Bank all believe that this blockchain is the first of its kind in the entire financial branch of Europe.\r\n\r\nAside from the banks the project is also joined by Ireland\u2019s Institute of Banking, storing credentials of over 23 500 workers in the banking sector.\r\n\r\nStoring and confirming credentials, certificates and other documents is one of the most promising ways to use the blockchain. The blockchain can store information so that no one can falsify or alter it, and can also be made open so that anyone can verify the information in it. Storing different certificates and documents in the blockchain ensures that companies can better trust the validity of these documents.\r\n\r\nThe project by Irish banks is set to be published in the year 2020.\r\n\r\n\r\n\r\n\r\n\r\nU.S. sanctions provoke North Korean hackers\r\nEconomic sanctions set by the United States have sparked North Korea to start new hack attacks in order to steal cryptocurrencies, informs Tonya Ugoretz from the FBI\u2019s cyber department. According to Ugoretz economic sanctions have had an impact on North Korea, which has led to the state using more resources for crypto-related hacks.\r\n\r\n\u201cSanctions are having an economic impact, so cyber operations are a means to make money and bypass these sanctions\u201d Ugoretz states.\r\n\r\nAccording to Ugoretz North Korea\u2019s crypto activity is not only limited to hacks, but the state has also initiated different crypto mining operations. She also informed that the FBI and other federal institutes have broad ongoing efforts to curb such activities.\r\n\r\nSome sources allege that also Russia and Venezuela, among others, would be using cryptocurrencies and blockchains to bypass U.S. sanctions, but these claims have so far not been supported by concrete evidence.
