1. Investing Without Research
Many beginners invest in crypto based on hype without understanding the project. This can lead to poor investment decisions.

2. Falling for Scams and Phishing Attacks
Scammers trick users into sending crypto or revealing private keys. These scams come in different forms, including fake giveaways, phishing emails, and malicious websites.
Example 1: A fake giveaway on Twitter promises to double your Bitcoin if you send some first. Many users fall for this trick and lose their funds.
Example 2: A phishing email looks exactly like an official exchange notification, asking you to log in. The fake login page steals your credentials and drains your funds.
Example 3: A scam website pretends to be a well-known DeFi platform, tricking users into connecting their wallets. Once connected, hackers gain access to withdraw funds.
How to Avoid It:
- Never share your private key.
- Verify URLs before logging into any crypto platform.
- Use two-factor authentication (2FA) on all exchanges.
