How to Spot a Rug Pull Before It Happens
Short answer

The warning signs are visible before the exit, and most of them can be checked in under ten minutes without technical skill.

Check who can move the money

Look at whether liquidity is locked, and for how long. Unlocked liquidity means whoever provided it can withdraw it at any moment, leaving holders with a token nobody can sell. This is the single most common mechanism and it is publicly checkable.

Then check whether the contract has functions allowing the creator to mint new tokens, pause transfers, or blacklist addresses. Any of these means the outcome is at one party's discretion regardless of anything else about the project.

Check who holds it

Heavy concentration in a few wallets means a coordinated exit is possible and easy. Look specifically for wallets holding large percentages that are not identifiable as exchanges or locked contracts.

Also check how the supply was distributed. A launch where insiders acquired most of the supply at negligible cost has built-in selling pressure at any price, and the people with the most information have the least reason to hold.

Check the human signals

Anonymous teams are not automatically fraudulent — plenty of legitimate crypto is pseudonymous — but combined with any of the above, anonymity removes the only remaining accountability. Copied documentation, a roadmap of vague milestones, and engagement that looks manufactured are all consistent tells.

Urgency is the strongest one. Sustained pressure to buy before a deadline exists to prevent exactly the checks described here. If you are being hurried, that is the finding — the rest is confirmation.

Frequently asked questions

Does this apply to stocks and commodities too?

The method does; the numbers do not. Levels, sizing and deciding in advance work identically across asset classes, but thresholds must be recalibrated — equities gap around earnings and only move during market hours, commodities trend more slowly, and currency pairs move a fraction of what crypto does, so a 1% move there is significant.
