Give the brothers in the crypto circle some confidence, I won't say any technical terms, just a simple explanation of the hope in encryption.

Encryption won't die because speculation won't die; at worst, it's still the best place in the speculative market, and funds will eventually come back.
The better scenario is that in the next wave of AI development, blockchain can be integrated, which would be a dual attribute of investment and speculation—funds not only come back but also come in even more.
This round of AI is mainly driven by supply-side shortages and is still in the infrastructure stage; only when it truly penetrates ordinary people's lives will the next wave come, and then encryption will have a chance.
Here's an imperfect analogy: it's actually like the second wave of mobile internet opportunities.
So, the future is bright, no need to worry, your main task is to avoid being scammed by fraudsters.
