In the cryptocurrency world, there are mainly three types of people who can make money:

1. Short-term trading experts: These traders primarily focus on spot day trading, watching the market almost every day, with frequent short-term operations and a high hit rate. Even when faced with adverse market conditions, they can remain calm and operate steadily.

2. Patient investors: They position themselves at low levels during bear markets, patiently waiting to sell at high points when a bull market arrives, usually achieving returns of several times their investment. However, this kind of persistence is very rare.

3. Technical veterans: This group is very adept at on-chain analysis and new projects, skilled in arbitrage and investing in new projects, gaining high returns through unique perspectives and accumulated experience. Some people can earn millions through arbitrage.

These different strategies and mindsets each have their advantages, and there are opportunities for profit in the cryptocurrency world.
