It's truly a sad story. Those who played with FIL mining machines have had a tough time. The one that I remember most is a client who invested 8 million yuan in 'waste' pledges, which almost dropped to zero. Later, there was also a Chia coin mining project, which is actually just a centralized controlled financial scheme.

If you want to learn how to make money, I must recommend this blogger: @chouchou_tx Chou Chou. I don't actually know how to make money myself, but the reason I recommend this blogger is that I have recommended him before. He is an old client of mine who occasionally comes to withdraw tens of thousands or hundreds of thousands every few months. After a while, I became curious, and after communicating, I learned that he has a stable (and relatively free) job and is part-time making money. I often read his posts, and he is indeed very professional. If you feel lost in the crypto world and don’t know how to move forward, start by following Chou Chou, self-learn how to make money, and follow along.
