Unlike primary market investment, which has obvious arbitrage space facing the secondary market, transactions in the secondary market are more free, open, transparent, and fairer. If we borrow Marx's theory of capital circulation, the primary market is like a production link, and the secondary market is like a free market transaction link, and surplus value can only come from the primary market.
  Of course, the actual situation is much more complicated than this. There are also many situations in the secondary market that damage its freedom and fairness, such as insider trading, market manipulation, and so on. In addition, financial products themselves can become financial capital, which can be used to capture surplus value by investing in the production links of the physical industry.
  In contemporary society, in the general legal sense, the manipulation of the secondary market is considered illegal, while the production of surplus value is considered legal. At the moment when the regulatory nature of the encryption field has not yet been clarified, the illegality of the former is difficult to be substantively investigated, resulting in the current situation in which the secondary market of the currency market is full of various market manipulation behaviors that undermine fairness and freedom.
  The income of the secondary market investment is basically derived from technological innovation and progress, and the resulting increase in social productivity. However, due to the widespread irrationality of the market, the secondary market is often full of opportunities to speculate on volatility under local time and space.
  Many people are not clear about what kind of investment they are participating in. They often enter the market with hindsight, fall into the zero-sum game of partial time and space in the secondary market, and become the reaped.
  Such a blind investment method, whether it is entering the stock market or the currency market, will probably have a similar ending. The so-called "do not know not to invest", although it originated from the stock market, it also applies to the currency market.
  Those who don't understand will find the currency market elusive and incomprehensible. However, the currency market, which is full of bubbles and scams, can gain greater transparency and penetration if it adheres to the principle of blockchain thinking.
