We usually think of “investment” as giving effort or money to someone. But investing is more about exchanging what you have for some value, and the object of the investment has some worth rather than just giving something away. Some exchanged values can be monetary or moral. If I swap my cash for moral and social benefits, it becomes a religious or social contribution. However, if the object of exchange is an asset with a specific monetary value or potential for profit, it is an economic investment. The world is designed to facilitate some form of value exchange. The main idea of investing is to trade low volatility for high volatility and then switch back to low volatility over time. The former is called an investment, and the latter is called an exit. Cash tends to be less volatile, while stocks and digital coins are very volatile. By exchanging assets with small volatility, stability is maintained, but wealth is not necessarily increased. - Joseph’s “just my thoughts”
For the security of the Internet service, we have been asked by the Internet service companies to set the password combined by more than 8 or 10 "uppercase letter+lowercase letter+number+special character". But it was obviously of no use. This security guideline was recommended by Bill Burr who worked at NIST in the USA, he suggested this way in his report. Furthermore, the user was required to change the initial password set regularly. Despite this measure, the best way of security to protect users' accounts was the notification of the alarm for attempted hacking when the hacker tried. We have only tried to change the keys despite the simple method meanwhile. Today, the world has begun to comprehend that the security problem is not encryption or confidentiality, but simply cyber-dominion control and communication. - Joseph's "just my thoughts"
