STUDY AT HOME ~ investment analysis & its procedure as tech hobby ~ Part 1
In the last two years during the covid-19 shock, many people would stay at home and think of a bunch of things in the time when they unexpectedly had. In my case, I took the amount of cash I would be able to earn in my life into account. I currently engage in a typical conservative company in Japan.
