I received a message late at night: "Teacher, the coin in my hand has doubled in three days, I have put all the money I have saved in the past six months, can I still increase my position?" "

Staring at the screen, my mind suddenly flashed back to that winter. At the end of 2017, in the partition room of an urban village in Beijing, I was wrapped in a military coat and stared at the market until three o'clock in the morning, with only about 100 bank cards left. washing dishes in the back kitchen of the restaurant during the day, and his hands are full of frostbite; When I came back at night to study the K-line, my eyes were as red as rabbits.

Now the account number has become eight digits, not luck, but a lesson from real money. The money lost in those years and the pitfalls that have been stepped on will be explained at once today.

**Skyrocket? That's a trap with bait**

Remember how crazy the market was back then. The aunts in the vegetable market were asking "which currency can rise", and I was holding the 80,000 yuan I had saved so hard, and my eyes were green - staring at an altcoin that had risen 320% in ten days. There is only one thought in my mind: I can double it to make up for the down payment on the house in my hometown.

I never thought about what it means to rise too fast.

On the third day, it opened directly and plunged 18% in a single day. A week later, 80,000 shrank to 20,000, and I squatted in the corridor and smoked a whole pack of cigarettes, my hands so cold that I couldn't hold the lighter steadily. That day I understood: a normal rise is like climbing a mountain, step by step; Crazy like bungee jumping, how cool it is to go up, how painful it is to fall.

Later, I set a dead rule for myself: coins with a short-term increase of more than 30%, if they do not go through 3-5 days of sideways consolidation, suddenly fall below 15%,
