Investment techniques involve converting labor income into financial income. In other words, it means purchasing an asset with money earned through labor so that the asset generates profit. But since assets are inanimate, how can they produce income? The answer is that you can profit from an asset’s changing value. You cannot profit if the value remains constant. If there were no volatility in assets, people would have to rely solely on labor to earn money. The issue is that you don’t buy assets that increase in value; you buy assets that decrease in value. Therefore, if you lack the perspective to judge the world, you should abandon the dream of building wealth through assets. - 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"
