Here is my list of 10 things you should not do when investing in cryptocurrencies:

1. *Don't do your research properly*: Don't rely on rumors or unverified news. Research the cryptocurrency's technology, team, mission, and goals.

1. *Don't invest more than you can afford to lose*: Cryptocurrencies are volatile. Don't risk your financial stability.

1. *Don't get carried away by FOMO*: Don't rush into investing for fear of missing out. Make informed decisions.

1. *Don't use weak passwords*: Protect your exchange accounts and wallets with strong passwords.

1. *Don't share personal or financial information*: Maintain your privacy and security.

1. *Don't ignore risk warnings from regulators*: They are designed to protect you.

1. *Don't become an unskilled "day trader"*: Trading requires experience and strategy.

1. *Don't neglect diversification*: Don't put all your resources into one cryptocurrency.

1. *Don't ignore news and regulatory developments*: Stay informed about changes in legislation.

1. *Don't hold on to an investment that doesn't work*: Be objective and don't get carried away by emotion.

These actions can lead to:

- Significant financial losses

- Security and privacy issues

- Incorrect informed decisions

- Legal and regulatory risks

- Stress and anxiety

Remember that investing in cryptocurrencies requires education, research, and caution.
