In the crypto world, if you only have three thousand yuan (about 400 USD), is there a chance to grow your funds?

The idea is actually quite simple: with small capital, if you want to grow quickly, trading contracts is the most efficient method, but the key is to control risk.
First stage: small capital amplification
You can use 100 USD as a single attempt fund, focusing on trading hot coins or mainstream coins' volatility opportunities, and you must set stop-loss and take-profit levels in advance.
The goal is not to multiply many times in one go, but to achieve phased growth, for example:
100U → 200U
200U → 400U
400U → 800U
Try up to three times.
Because the crypto market has an element of luck, if you keep going all-in, it's easy to make profits initially but face liquidation in the last attempt.
If you successfully complete all three attempts, your funds could reach over 1,000 USD.
