Digital Currency

  “Digital Currency” Recently, Digital Currency is proceeding, but limited to wallets for purchase. To proceed more, digital currency must be applied to assets classes. Then, paper and coins currency can be invalid. If digital currency is applied to assets and used in smartphones, various types of Bonds and Securities are possible. Digital Currency is associated with Personal Information, and it causes fear and intrust to own government for some people. This problem can be solved by fear to lose money. If paper and coins are invalid, people must use digital currency. To proceed Digital Currency, deleting trust for Bitcoin is good way. Bitcoin is used for dark money, and not in control by trustable organizations. Digital Currency by government can compete Bitcoin if the government is trustable. In addition, Bitcoin has several deep security risk by hackers. Roll back is impossible when hackers steal Bitcoin.

The "MORE"

  2021/7/26.  The “more” or “more than or equal to” I met one difficult problem. The original story(English) is below site’s problem. And changed story(Japanese) includes changed rule. I think that this change is from mistranslation. But this change causes the problem MORE difficult. The original story http://www.bigriddles.com/riddle/ten-pirates-and-their-gold [The problem part] Each pirate will vote against a proposal if they know that they would end up with more gold if that proposal were to fail. [Changed rule] Each pirate will vote against a proposal if they know that they would end up with “more or equal to” gold if that proposal were to fail. It is a miracle difficult problem caused by mistranslation. “より大きい” corresponds to "more than". “以上” corresponds to "more than or equal to". “未満” corresponds to "less than". “以下” corresponds to "less than or equal to". In addition to the model answer, there are the following answ

Cheaper economy in Japan

  2021/7/16.     Cheaper economy in Japan   I ate alone dinner at Yayoiken in Japan. https://www.yayoiken.com/en_files/regular_menu_pdf/88_2021.07Regular_EN_0706.pdf?id=2281 Hummm. It costed ¥780, approximately US$7.10. Is this too cheap? I ate at Tokyo Ginza in Japan. I don’t want to tell how good taste it was or how beautiful the dinner was.(And it was not so beautiful, just only one meal.) What makes it so cheap? Law of one price seems to have strong power in Japan. https://en.m.wikipedia.org/wiki/Law_of_one_price I think that law of one price prevents raising price in Japan. I want to think more deeper about this topic, later.

The "追い貸し"

  2021/7/8.  “ 追い貸し” “追い貸し” refers to the extension of the life of bad company that should normally leave the market by the bank by making additional loans. Additional loans to bad company or government for extension of their life… “追い貸し” is similar to debt trap, but more clever. I feel that “追い貸し” is being done to USA government by other governments or non-native USA investors. Simply, USA government can’t return their debts, so that they have to cut government costs or USA interest rates raises. But none of them occured. This is because of “追い貸し”. “追い貸し” keeps on until USA government give up. In additional simulation, I think that next USA President will be Mr.Trump. Because if the USA stock & bond market crash, the society will be confused. At that time, he gets that position.
