When we see two players, we can say that they are playing a zero-sum game. Because in most cases, there will always be winners and losers. If we calculate the winner as 1 and the loser as-1, then the sum of the scores of two people is: 1 (- 1)=0.

This is the basic content of "zero-sum game": players lose and win, and one side wins just as the other side loses, and the total score of the game is always zero.

The principle of zero-sum game is widely concerned, mainly because people find that similar situations can be found in all aspects of society, and the bitterness and bitterness of losers are often hidden behind the glory of winners. From individuals to countries, from politics to economy, it seems that the world is a huge "zero-sum game" field. This theory holds that the world is a closed system with limited wealth, resources and opportunities. The increase of personal, regional and national wealth inevitably means the plunder of others, regions and countries. This is an "evil evolution" type of law of the jungle world.

Stocks, futures, lottery tickets, funds, etc. in the tide of world economy all have the color of "zero-sum game", that is, the total investment is regarded as zero, and the rest is the problem of how to allocate it as a whole. If there is a profitable party, there must be a losing party! Investors who participate in playing these tickets follow this principle. "Zero-sum game" itself will not produce benefits to social production, which is completely similar to gambling.

Of course, it has changed the taste for listed companies to obtain development funds by means of zero-sum game. This is an important reason why governments around the world openly allow such a "zero sum game" to exist!

Warning those who rely entirely on "zero-sum games" to get rich, danger is such an act, which is not much different from gambling!
