Trade without thinking about eating the whole fish from head to tail!

The fish head is tough to chew, and the tail has many bones, making it easy to get stuck in your throat if not eaten properly.

Only eat the fattest part of the fish,

Avoid guessing the bottom, don't try to catch the top, and follow the trend,

This is the way to sustain long-term survival.

Fish head: Guessing the bottom, high risk, small profit

• Fish tail: Betting on the top, easy to get caught, easy to "get stuck in your throat"

• Fish body: Clear trend, safe and comfortable, the thickest profit

Only eating the fish body and not greedily going for the head or tail is the key to stable profits.
