The rise of popularity is fast, and the fall of popularity is also fast. The web2 internet celebrity economy is an example. Every time someone asks me about my experience in starting a WeChat account, I always want to laugh. If I had thought about it, I wouldn't have been doing it for three years and only had 100000 followers. I can't give any advice. Also, those who come to participate in gold and cryptocurrency trading are welcome, while those who come to extract liquidity are kindly advised to stay away.
