Inevitably, those who dabble in investing easily will suffer serious burns.

Last time, I introduced some basic laws for investing to live without dying. Let's review.

First of all, as a general principle, "returns are small when you switch to something with a more general value, and you get a big return when you switch to something with limited value."

He also said that by "making good use of services with which we have a long-standing relationship" and "taking time and effort on your part," you can avoid losses and gain benefits.

In addition, I wrote that it can be said that "If you use it anyway, it is better to use a major company, a service that has many stores nearby (or there are stores nearby), or a service that you know well."

How to efficiently increase 1 million yen in cash?

Let's continue to think about money and value based on these laws. First, let's say you have $100,000 in cash. When thinking about how to increase this 1 million yen, the most secure, safe and easy to collect is a bank savings account.

Simply put, depositing money in a bank means that the depositor is lending money for the bank to lend to others. You can withdraw and collect your money at any time if you have an ordinary deposit, but the interest rate is very low.

You can make a profit of 10 yen by depositing 1 million yen for a year. It may sound silly, but if you can always deposit (i.e. lend to the bank) and be ready to withdraw (i.e. the bank has to pay you back), that's about as much as you can get.
