As a delivery man, I may not know as much about cryptocurrency as professionals, but I can briefly introduce CHZ coin.

3. **Investment value**: As a cryptocurrency, CHZ coin has investment value, and its price is affected by factors such as market supply and demand, sports events and fan engagement.

4. **Security**: CHZ coin transactions and holdings may need to be carried out through encrypted wallets. To ensure the safety of funds, users need to take appropriate security measures, such as using strong passwords and two-factor authentication.

5. **Participation Method**: As a delivery person, I may be exposed to CHZ coins by participating in voting for certain sporting events or purchasing fan tokens.

It should be noted that there are risks in the cryptocurrency market, including price volatility and potential fraud. Therefore, before considering investing in or using CHZ coins, I recommend conducting sufficient research and making decisions based on your financial situation and risk tolerance. At the same time, remain vigilant and avoid participating in any unverified projects or investment opportunities.
