We'll teach you how to spot and avoid these scams such that you can protect your investments. Most common of all scams involving cryptocurrencies include the actions below. They are explained in what will follow. 

1. Phishing Attacks 
How it works: Scammers impersonate legitimate platforms (e.g., Coinbase, MetaMask) via fake emails, websites, or social media messages. 

Goal: Steal login credentials or private keys. 

Red flags: Urgent language, misspelled URLs, unsolicited requests for info.

Fake Giveaways and 'Free Crypto' Scams: This is how it goes: Fraudsters impersonate celebrities or influencers (e.g. Elon Musk, Vitalik Buterin) claiming that sending money on the first brings "double your money." 

Goal: Tricking victims into making irreversible payments.

Red flags: Too-good-to-be-true promises, phony verification badges.

c) Ponzi & High-yield Investment Plans. The plan works in this way: Scammers promise transfers unrealistically (for instance "10 percent daily profit") but pick early investors with funds from new victims. 

Goal: Falling off the map with deposits once the scheme collapses. 

Red flags: Guaranteed returns, considering lack of transparency and pressure to recruit others. 

d) Rug Pulls (Exit Scams) 
How it works: Developers hype a new token, draw in investors, and then bail the course while draining liquidity. 

Goal: Cash out before the token crashes. 

Red flags: Anonymous teams, locked liquidity, no audits. 

e) Fake Wallet Apps & Malicious Software 

Install the fraud app on Google Play or Apple Store, and then it steals seed phrases when downloaded. 

Goal: Empty the wallets belonging to the victims. 

Red flags: Unpopular source, fake reviews, and no downloads. 

2. How to Protect Yourself 
a) Verify Before You Trust Only: Check, for Instance, "coinbasse.com" Against "coinbase.com". Use official websites/apps-never click links from unsolicited messages. 

b) Never Share Private Keys or Seed Phrases Most legit services will not ask for this. Keep them offline (hardware wallets or encrypted backups). 

c) Investigate Projects Thoroughly Check the audits (CertiK, PeckShield). Look for doxxed teams (real identities, LinkedIn profiles). Stay away from "pump and dump" groups. 

d) Enable Security Features 2-factor authentication (2FA) by an authenticator app (not SMS). Whitelisted wallet addresses on exchanges. 

e) Be Wary of "Guaranteed" Profits: If it sounds too good to be true, it is. 

To prevent FOMO (Fear of Missing Out) from ever creating a sense of urgency, use a safe platform where your crypto will never go missing. 

3. What You Should Do If Scammed Act on it quickly: Shift remaining funds into a new wallet. Report the scam: Have it filed by. IC3 (FBI's cybercrime division): local authorities warn others, providing all details in the crypto community in order to further detract victims. 4. Future-proofing one's crypto security. Have large holdings kept in hardware wallets (Ledger, Trezor). Monitor transactions with blockchain explorers (Etherscan). Be very well clued in on new scams (follow cybersecurity experts). 

Conclusion 
Scams are rampant in crypto but awareness is the best weapon against it because keeping vigilant and verifying sources as well as keeping your assets secure minimizes the chances of uncertainty while investing.
