This marks a rise of roughly 68% compared to the year 2019, when a similar survey for wealthy investors was last conducted. The survey was composed of participants with at least 1 million British pounds, which equals approximately $1.32 million dollars. The participants were selected from around the world, including the United States, the United Kingdom, Australia, Latin America, Asia, Africa and the Middle East. \u201cAs the survey shows, this impressive performance is drawing the attention of wealthy investors who increasingly understand that digital currencies are the future of money and they don\u2019t want to be left in the past,\u201d reports Nigel Green, CEO of deVere Group. The world\u2019s wealthiest have in recent years found Bitcoin and cryptocurrencies. Miner profits reach yearly highs The revenue from Bitcoin mining has reached a yearly record. On the 18th of November daily BTC mining profits peaked at $21.2 million dollars. This broke an earlier record from the 6th of May, when the revenue was roughly $20.6 million per day. During May the profitability of mining plummeted in the wake of Bitcoin\u2019s block reward halving. Back then bitcoin\u2019s price was moving around $9\u00a0000 dollars. At the moment the price is roughly double at $18\u00a0000 dollars a piece. Aside miner revenue, also the Bitcoin network\u2019s computing power is close to a new record. Right now the hash rate is approximately 143.3 exahash per second. The earlier record is from October, when the hash rate was recorded at 157.6 exahash per second. Mining profitability has grown despite the recent block reward halving. Number of BTC addresses growing The number of Bitcoin addresses is growing, reveals data by Glassnode. On the 18th of November a whopping number of 25\u00a0000 new BTC addresses were created every hour. Last time new BTC addresses were created at such a rapid pace was in January 2018, when bitcoin\u2019s price was even higher than right now. The all-time record was on the 21st of December 2017, when new addresses were created up to 600\u00a0000 within a single day. The number of Bitcoin addresses does not directly correlate with the number of users, since users can in theory have multiple different addresses. Different services and apps can also generate several new wallet addresses for users. Nonetheless, the growing number of addresses is a strong indication that also the number of Bitcoin users is growing. The numbers also suggest different Bitcoin services and apps are currently used more than in years. Bitcoin wallets can be created unlimitedly, but most users only have a few.

Pliego also encouraged his followers to get acquainted with Bitcoin and read related literature such as The Bitcoin Standard. The Bitcoin Standard has also been translated to other languages such as Spanish and Finnish. Pliego did not stop at praising bitcoin as an investment, but also continued to elaborate on its political dimensions. Pliego believes that bitcoin can effectively protect citizens from the intervention of states or other parties. As an example he mentioned Venezuela, where citizens have increasingly turned to Bitcoin to protect themselves from the country\u2019s failed financial policy and hyperinflation. According to Ricardo Pliego fiat currencies are worthless compared to bitcoin.

The central bank of Japan has announced launching the digital yen in the near future as a response to rapidly evolving financial technology reshaping the world. The group also includes the three biggest private banks in Japan. These financial companies including Mitsubishi UFJ Financial Group, Mizuho Financial Group and Sumitomo Mitsui Financial Group have earlier developed their own financial technologies and digital currencies. In the now commencing experiment they will test out common platforms for using the digital currency. \u201cJapan has many digital platforms, none of which are big enough to beat cash payments. We don\u2019t want to create another silo-type platform. What we want to do is to create a framework that can make various platforms mutually compatible,\u201d states Hiromi Yamaoka, chairman of the group. While Japan is traditionally regarded as a technological superpower, the nation still heavily relies on cash. Digital payments only comprise 20% of Japan\u2019s payments, which pales in comparison to China with 75% of digital payments. One objective of the digital yen project is to encourage Japanese to move from cash to a modern digital currency.
