Rug pulls & scams: the red flags
Most crypto losses aren't bad trades, they're scams. A "rug pull" is when a token's creators drain its value and vanish. The good news: they nearly always leave the same fingerprints.
The classic red flags
- Unlocked liquidity. If the team can withdraw the pool, they can pull the floor out overnight. Look for locked or burned liquidity.
- A mint function. Contract code that lets them create unlimited new tokens = instant dilution to zero.
- Holder concentration. A few wallets holding most of the supply can dump on everyone else.
- Honeypot. The contract lets you buy but blocks selling. Always simulate a sell first.
- Anonymous team + hype. No accountability plus manufactured urgency ("get in now") is the oldest pattern there is.
How to check
- Read the contract on a block explorer; use a token-scanner for mint/liquidity/tax flags.
- Check the holder distribution and whether liquidity is locked.
- Learn to read the code, the real defence: smart-contract safety (Cyfrin).
If you can't explain where the yield or the value comes from, assume you're the yield. Slow down; the good opportunities survive due diligence.
