As an old hand in the crypto world with years of experience, here are a few heartfelt suggestions for newcomers:

1. Don't touch contracts during the day; after 8 PM is golden time.

The market fluctuates greatly during the day, and it's the favorite time for manipulators to cut down newcomers. The market is relatively stable at night, making it easier to see trends. I've suffered losses during the day too many times; now I only operate at night.

2. Take profits and run, don't be greedy.

Remember: cashing out is safe! I've seen too many people make a profit on one trade and want to make a second trade, only to give all their profits back. Set a take-profit point and stop at that point.

3. Better to miss out than to short.

The risks of shorting are much greater than going long, unless you are absolutely sure. It's best for beginners to only go long and consider shorting once they have more experience.

4. Be flexible while watching the market.

If you have time to watch the market, don’t set a fixed stop-loss; manipulators love to sweep stop-losses. But if you don’t have time to monitor the market, you must set one to prevent margin calls. I learned this lesson the hard way, costing me 50,000 USDT.

5. Regular withdrawals are the way to go.

Withdraw a portion of your profits; don’t leave everything on the exchange. Last year, I made 200,000 but didn’t withdraw, and then lost it all in a big drop. Now I withdraw 5% for every 10% I earn, allowing for a much more peaceful sleep.

6. There are techniques for reading K-lines.

For short-term trading, look at the 1-hour K-line; if there are two consecutive upward movements, go long; if there are two downward movements, go short. During sideways markets, look at the 4-hour and daily charts to determine direction. This simple method has saved me a lot of money.

7. Diversify investments for safety.

Never put all your money into one coin. I now divide my investments into 5-6 positions, operating in different directions. This way, even if one direction is wrong, it won't cause significant losses.
