CZ shares three questions about investment: Can we hold on to zero? Former Binance CEO Zhao Changpeng (CZ) proposed in a post that risk management in cryptocurrency investment should focus on three points: One is to evaluate the worst-case scenario, whether the asset can maintain the lifestyle if it returns to zero; The second is the number of attempts that one can tolerate; The third is whether one truly understands the project being invested in, and if not, one should actively learn.
