The 90% Rule: The 7 Checks That Catch Almost Every Rug Before You Buy

Here is a number that should terrify you: over 90% of tokens launched on Solana and BSC in the last year are dead within a week. Not down. Dead. Zero liquidity, zero volume, zero chance of recovery. The degens who bought in didn't lose to bad charts or unlucky timing — they lost to patterns that were visible on-chain for hours before the collapse. The system that catches almost all of it is a checklist I call The 7-Gate Screen, and by the end of this guide you will have the exact thresholds, exact numbers, and exact tab-by-tab walkthrough to run it in about sixty seconds on any token. Ninety percent of scams die at Gate 2 alone. Almost nobody runs it. You're about to be in the ten percent who read like a forensic analyst instead of gambling like a tourist.
🔍 Gate 1: Top-10 Holder Concentration — The First Red Flag
Open any token page on GMGN and look at the holders panel before you read a single tweet about the project. The number that matters: percentage of total supply held by the top 10 wallets.
Under 20% — healthy distribution. A rug is structurally unlikely because no single cluster can dump enough to kill the chart.
20-40% — caution zone. This is normal for newer launches, but you need the next gates to pass clean.
Over 40% — walk away. Full stop. If ten wallets control nearly half the supply, they are the market. When they decide to exit, there is no bid deep enough to catch the fall. On Solana launches you will frequently see this number sitting at 60-80%, and the chart looks amazing until the exact block where it doesn't.
The "most people get this wrong" callout: a low top-10 percentage does NOT mean the token is safe. It is one gate in a sequence. But a high one is an automatic disqualifier regardless of how good the rest looks.
🔒 Gate 2: LP Locked vs Burned — Where the Exit Liquidity Actually Lives
This is the gate that kills nine out of ten scams. Go to the Security tab on the token page. You are looking for two things: the amount of liquidity paired with the token, and what happened to the LP tokens.
Liquidity (LP) tokens are the keys to the exit door. If the team holds them, they can pull the entire pool at any second and leave you holding a token that trades against nothing.
LP burned — the keys are destroyed. The liquidity is trapped forever. This is the gold standard.
LP locked — the keys are in a timelock contract. Acceptable only if the lock is six months or longer and the lock contract is verified. Anything under three months is suspicious; under one month is a countdown timer to a scam.
LP unlocked, held by deployer — instant disqualification. No exceptions. This is the single most reliable rug predictor in all of crypto.
The contrast to remember: a token can have a brilliant chart, a massive community, and a verified contract — and still be a one-way ticket to zero if the LP is unlocked. The chart is a marketing artifact. The LP status is structural fact. On GMGN's security tab this is displayed in the top block. Read it before you read anything else.
⛓️ Gate 3: Mint & Freeze Authority — Can They Print More?
Still on the Security tab. You are checking whether the token contract has mint authority and freeze authority enabled.
Mint authority renounced — the supply is fixed. Nobody can print new tokens into existence and dilute you into dust. This is required.
Freeze authority renounced — the contract cannot freeze individual wallets. This matters because a malicious token can freeze every holder except the team, then rug the rest.
Mint authority active — the team can mint infinite supply at any moment. Even if they promise they never will, the capability itself is the risk. A token that can be diluted infinitely is not an investment; it is a promise not to steal from you.
Red-flag logic that most people miss: teams that run "fair launch" tokens with active mint authority are not being flexible — they are being dangerous. You are betting on their restraint, which is the one asset no scammer has ever lacked the ability to fake.
🧾 Gate 4: Buy & Sell Tax — The Asymmetry Trap
Scroll to the Tax field on the token detail panel. You want two numbers: buy tax and sell tax.
Healthy tokens run 0-5% on both sides. Some legit projects charge a 5-10% buy tax for marketing or development wallets — checkable, explainable, and fine if disclosed.
The asymmetrical pattern is the tell: low buy tax to lure you in, high sell tax to trap you. A 5% buy / 25% sell token is not a project — it is a tollbooth. You pay to enter, and the exit fee is engineered so that breaking even requires a price pump that the same structure makes nearly impossible.
The cynical math most people skip: if the sell tax is 25%, the token needs to rise 33% just for you to get your principal back after one round trip. Most tokens in this category never print that pump. You are not trading; you are donating.
Sell tax over 15% is an automatic skip. Buy tax over 10% without a clear, verifiable purpose is an automatic skip.
🧪 Gate 5: Bundler & Sniper % of Supply — The Insider Take
Back to the top-10 holders list, but now you are reading it differently. On GMGN's holder breakdown, you can see how many of those holders are flagged as bundlers or snipers — wallets that bought in the same block as the pool opened, or in the first few blocks after.
Bundler percentage under 5% of supply — the launch was mostly organic. Green.
Bundler + sniper combined over 15% — red flag. These wallets did not discover the token through research. They were positioned before the public could buy. Their cost basis is near zero, which means they can dump at any price and still print profit.
The contrarian reframe: a token with a huge early sniper presence is not "hot" — it is prey-rich. The snipers are not buyers of conviction; they are hunters of exit liquidity, and you are the liquidity. When they distribute, the chart does not dip — it compresses. Sniper-heavy launches have a statistical tendency to make a lower high and then trade sideways as the insiders bleed out. You are holding a bag that was filled by people who needed you to hold it.
👤 Gate 6: Dev Wallet History — Who Is Behind the Contract?
GMGN shows you the deployer wallet and its history on the token page. Spend forty seconds on this. The question is not what the dev says — it is what the dev's wallet has done.
Deployer wallet is fresh, funded from a mixer, and has launched three other tokens this month — that is a serial launcher. The pattern is a lottery ticket factory. Each token gets the same playbook: hype, pump, dump, repeat.
Deployer wallet has history of rugged projects — automatic disqualification. The flag exists for a reason.
Clean dev history with a single, older launch — neutral to positive. Not a guarantee, but the absence of a scam trail is meaningful.
The principle most people resist: a brand-new contract deployed by a brand-new wallet funded minutes before launch is a scam-shaped object. It is possible the team is just privacy-conscious or technically fresh — but the base rate is brutal. You do not need to find the dev's face or dox. You need to see a wallet that has not victimized a chain full of people before your turn.
💧 Gate 7: Liquidity vs Market Cap Ratio — The Exit Depth Test
Final gate, and the one that separates "risky trade" from "trap." Take the liquidity figure and the market cap from the token page and compute the ratio.
Liquidity at or above 10% of market cap — you can exit meaningfully at any price. The pool is deep enough to absorb selling.
Liquidity between 3% and 10% — thin, but tradable with size discipline. Keep position small.
Liquidity under 3% of market cap — the price is decoration. A market cap of $2M with $40K of liquidity means the first wave of sellers converts the chart to air. This is the classic low-float, low-liq scam structure: massive paper value, zero real exit.
Honeypot cross-check: if you cannot sell at all — transaction reverts, or the contract blocks certain addresses from selling regardless of price — you are in a honeypot. The Security tab flags known honeypot patterns directly. If you see that flag, the article ends here for that token. Nothing else matters. You are not trading it; it is trading you.
⚡ The 60-Second Run, In Order
Here is the complete sequence on a fresh GMGN token page, timed:
- Security tab: LP burned or locked 6+ months? Mint + freeze renounced? Honeypot flag absent? (5 seconds)
- Tax field: Both sides under 10%, sell side under 15%? (3 seconds)
- Top-10 holders: Under 40%? (3 seconds)
- Bundler/sniper %: Under 15% combined? (5 seconds)
- Deployer wallet: No rug history, not a serial launcher? (10 seconds)
- Liquidity/MC ratio: At least 5%, ideally 10%+? (5 seconds)
- Chart read: Not up 300% in the last hour on thin volume? (5 seconds)
Fail any gate, walk. Fail two, you are gambling, not trading. Pass all seven, you still have a risk — but you have eliminated the category of risk that takes everything.

🎯 Bottom Line
The market does not reward bravery. It rewards asymmetric information, and the information in this guide is the difference between a trader and a spectator. The seven gates are not a guarantee — no checklist is — but they are the cheapest insurance you will ever buy against the most common way money disappears in crypto. The token that passes all seven still has market risk. The token that fails any of them has structural risk, and structural risk is a decision you make before you click buy.
Most people will skip this checklist because it is boring. The top 10% run it in sixty seconds on every single launch, every single time, no exceptions. That is the whole edge. Rugging is a business, and businesses study their marks. Stop being a mark. Run the gates, respect the numbers, and let the scams filter themselves out while you focus on the ten percent of launches that deserve your attention.
Read the token like it is trying to take your money — because it is. The readers who do that are the only ones who keep it. DYOR, verify every threshold yourself, and never trust a single source — including this one. The chain is the truth. Everything else is marketing.
