In the field of Crypto Assets, the market cap generally refers to indicators that reflect the overall market trends, similar to how indices reflect the overall stock market. It can be understood as a comprehensive view of the prices of many Crypto Assets, looking at the overall performance of the market.

- Reasons for fluctuations

- Market Rise: More buyers than sellers, with a significant influx of funds into the market, or major positive news in the industry (such as breakthroughs in new technology or supportive regulatory policies), driven by substantial purchases from leading institutions.

- The market is down: Heavy selling pressure, possibly due to negative news (tighter regulations, security vulnerabilities), causing panic selling in the market; or major players are unloading, resulting in a large number of coins being sold off.

- Long and Short vs. Market: "Long" refers to bullish actions such as buying, expecting to profit from a price increase; "Short" refers to bearish actions such as selling or shorting, hoping to make money from a price decline. The comparison of long and short forces affects the market; if there is strong buying pressure from the long side, the market may rise; if there is strong selling pressure from the short side, the market may fall. However, the market is not simply a sum of long and short positions; it is also influenced by various factors such as market sentiment, macroeconomic conditions, and industry trends.
