CZ reveals crypto millionaires' secret In a tweet published earlier, Zhao also revealed “a little secret” of all crypto millionaires he is familiar with. CZ claims that all they had to do was not to panic-sell their crypto when prices went down in a sharp fall. “A little secret about all the crypto millionaires I know... they all had to hold through dips,” CZ tweeted. He concluded his message, stating that he also knows one crypto billionaire who turned into a millionaire just because he sold part of his crypto during a dip following the panicking crowd. A little secret about all the crypto millionaires I know... they all had to hold through dips. The only exception was ... a guy who was a billionaire.
