All coins, two heads and two tails at the same time, do not appear. This probability is only one eighth of that of six coins. This small probability shows that coins are not thrown out casually, but put down artificially.

Investment is like a coin. You can't invest all your money in one basket. The two sides of a coin are equivalent to two competitors, such as Coca-Cola and Pepsi. Allocating funds equally to these two enterprises can effectively avoid risks. Because the whole market is really growing, no matter how the market share of Coca-Cola and Pepsi is divided, in the end, your total investment will always increase.

In addition, the denomination distribution of coins is very uniform, which is the same as investment. Part of it is a block, which is the main body of investment income. It should be a stable income from long-term investment. The other part is 5 cents, which is used to get better returns as much as possible under the condition of controllable risks in the medium term, and the last part is 2 cents for moving, which is used in short-term and greater risks.
