You only know that Li Xiaolai was once the Bitcoin billionaire, but you don't know the kind of melancholy when he bought 2,100 BTC at an average price of 6 dollars in 2011, and then it fell below 1 dollar, resulting in a 97% reduction in his assets.

You only know that Zhao Changpeng made it onto the Forbes Billionaires List, but you don't know that in 2014, he sold his house in Shanghai and went all in on BTC, only to regret it helplessly when it subsequently fell sharply.
You only know that Zhao Dong is a big player in over-the-counter trading, but you don't know that in 2013 he bought 2000 BTC with 1 million, turning it into assets worth over 100 million. After three futures liquidations in 2014, resulting in a total loss of 150 million and debts of 60 million, he survived, and that is spring!
Now, you only know the immediate benefits, but are unaware of the future market value!
In this industry:
1. There is no bottom to the fall.
2. The rise has no bounds.
3. If you can't handle the panic of turning 1 million into 100,000, you won't enjoy the rewards of turning 1 million into 1 billion.
