At present, I have found that some important figures at the top of the food chain in the cryptocurrency industry, such as CZ, the founder of Binance, Sun Yuchen, the founder of Tron, and the founder of MicroStrategy, are highly optimistic about and encouraging everyone to buy Bitcoin on Twitter. This behavior makes me question whether they are encouraging investors to enter for their own benefit in order to 'harvest leeks', or sincerely hoping that we can invest in Bitcoin and make significant profits.
