Stocks should be bought cheaply and sold at a high price to make a profit. Therefore, it is said that timing—specifically, the timing of buying low and the timing of selling high—is a key factor. However, the issue is that I can’t predict the timing. It’s similar to how we can’t know what the weather will be like a year from now in our area. It’s wise to assume that the best approach is to acknowledge our uncertainty about timing. Attempting to time the market is a common trap for stock investors. Consider this: if you could know the timing, you would be the wealthiest person in the world. The advantage of long-term investing is developing the ability to identify stocks that are likely to appreciate over time, despite the fluctuations in stock prices, and investing in their value. The choice is yours. - 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"
