How to easily earn 200-3000 yuan daily in the crypto world?

There have always been crypto friends saying: the price of coins fluctuates greatly, with profits rising and falling, making it hard to bear; I really want to know if there are any profitable methods in the crypto world that have good returns and lower risks. Believe it or not, there is indeed such a method, and that is arbitrage.
1. What is arbitrage?
Li Ka-shing once said: The essence of business is "buy low and sell high." "Buy low and sell high" means purchasing goods at a lower price and then selling them at a higher price to make a profit, commonly referred to as "scalper" or "middleman."
The same principle applies to arbitrage:
The same coin can have price differences across different exchanges. By buying at the exchange with the lower price and selling at the one with the higher price, one can earn the price difference. This can yield profits regardless of whether it's a bear market or a bull market, and the risks are relatively low. This kind of low-risk arbitrage operation is called "搬砖" in the crypto world.
2. Reasons for the Emergence of Arbitrage Opportunities
Many people have such doubts: Nowadays, the speed of information flow is so fast that price differences can be easily discovered, and some people who specialize in arbitrage even use quantitative trading robots, which are a kind of black technology. So how are arbitrage opportunities generated?
