Crypto Rug Pulls Explained: What They Are and How to Avoid Them

Open a crypto wallet and scoop up a freshly minted token on a decentralized exchange (DEX). A DEX is a peer-to-peer marketplace that lets traders swap assets directly on the blockchain — no bank or broker in the middle. That hair-trigger convenience is exhilarating, but it’s also a breeding ground for fraud. Crypto rug pulls have cost investors billions. By learning how these scams work, spotting their warning signs and sticking to a few protective habits, you can keep your coins from becoming someone else’s exit strategy. 

Crypto Rug Pulls 101: Scams That Can Drain Your Wallet Overnight

A rug pull is a sudden exit in which project insiders — usually the developers or liquidity-pool controllers — strip value from a token and disappear. Bankrate groups the playbook into three moves — insiders dump their own tokens after hyped marketing, remove most or all liquidity from the pool or hide “sell-blocking” code in the smart contract that only shows itself when you try to cash out. 

Unlike phishing, you willingly deposit funds and trust the project’s smart contract. Because transactions are on-chain, the exit can happen in seconds while victims watch the numbers drop on a block explorer.

How to Spot a Rug Pull Before It Happens

Before the list of rug pull crypto, remember this — legitimate teams welcome transparency because it lowers their cost of capital. Pushback on scrutiny is a red flag by itself. Watch for these signs:

• Anonymous or unverifiable founders: Pseudonyms are acceptable, but serious builders leave a track record.
• Unlocked or tiny liquidity pools: If liquidity isn’t time-locked, one wallet can drain it instantly and crash the price. 
• Code that blocks selling: Use a small test transaction. If you can buy but not sell, run.
• Sharp, thin-volume price spikes: A 1,000% candle with just a handful of holders screams manipulation.
• No third-party audit: In Q3 2023, 85% of rug pulls tracked by security firm Hacken were not audited at all. 
• Yields that defy math: Triple-digit annual percentage yields without clear revenue usually mask a Ponzi. 

Why Age Doesn’t Guarantee Safety

The U.S. Federal Trade Commission notes that adults aged 18-59 report 86% of online shopping scam losses, yet situational factors mean seniors often lose more per incident. Put simply, scammers craft different lures for different age groups, and a rug-pull contract doesn’t care how old you are. 

Real-World Crypto Rug Pulls That Shook Investors

These stories began with slick marketing, glowing community chats or political endorsements. None of the victims expected to exit liquidity the night before the collapse. Each example drives home the same lesson — hype means nothing without verifiable, on-chain transparency. 

Hawk Tuah ($HAWK)

Viral video star Hailey Welch’s meme coin hit a $500 million market cap in hours, then cratered over 95% after on-chain sleuths spotted a tight cluster of wallets controlling 96% of the supply. Bubblemaps later showed those wallets dumping into thin liquidity. At the same time, the team raked in roughly $2 million in trading fee revenue — prompting furious holders to demand refunds during a chaotic Twitter Space that Welch abruptly left. 

LIBRA

A single post from Argentina’s president sent LIBRA rocketing past a $4 billion valuation, but insiders emptied the pools within hours — erasing nearly $250 million. The scandal snowballed into a fraud lawsuit, a congressional inquiry and even a court-ordered freeze of $58 million in USDC linked to the development team — evidence that political hype can mask classic cash-out mechanics. 

OneCoin

Marketed for years as the Bitcoin Killer, OneCoin never ran a real blockchain. U.S. prosecutors estimate investors poured more than $4 billion into the scheme. Co-founder Karl Greenwood was jailed for 20 years and ordered to forfeit $300 million, while fellow founder Ruja Ignatova remains on the FBI’s Most Wanted list. The case proves courts will chase crypto fraud across borders over decades.

Squid Game 

Leveraging buzz from the show’s new season, scammers relaunched SQUID on the Base network and then rugged it within three hours — price dropped from $0.14 to effectively zero or a 99% wipeout. PeckShield’s alert came too late — the deployer held most of the supply, dumped at peak and vanished. 

Tips for Dodging Crypto Scams

Before you hit the “buy” button on any new token, run through these common-sense checks:

Review the contract

Open the token’s contract in a public block-explorer site and click the Read/Write panel. Scan the transfer-related functions for words like onlyOwner, blacklist or whitelist — any code that lets one wallet freeze or block sales is a red flag. If you don’t read Solidity, hire a vetted auditor on a gig platform and make contract review a fixed cost of doing business. 

Confirm that liquidity is truly locked

Find the lock address on the pair’s liquidity page that holds the LP tokens and check the unlock date. A valid lock shows a timestamp months or years in the future. Reject pools that can be unlocked at any moment or that sit in wallets controlled by the developers. A genuine time-lock means the creators can’t yank your exit liquidity while the project is still young. 

Inspect holder distribution with an on-chain analytics dashboard

Open the token-holders list and note how much supply the top 10 wallets control. Developers who hold at least 30% of the supply can easily dump and crash. Ensure a burn or dead address holds a chunk of the supply — not a private wallet. A lopsided distribution tells you insiders could dump and crush the price in one transaction. 

Spread risk across chains and wallets

Keep long-term holdings on a hardware wallet and use a separate hot wallet for day trading or experimental tokens. Treat every new blockchain ecosystem as a silo — what happens on one chain shouldn’t sink your entire portfolio. This compartmentalization limits the blast radius of any single failure. 

Bookmark official web addresses

Copy the project’s site or app link directly from its whitepaper or verified announcement and save it as a bookmark. Always navigate through that bookmark instead of search engines — which can surface lookalike phishing pages. Before connecting your wallet, double-check that the URL and SSL certificate match the official domain. 

Stay active in the project’s public channels

Follow the developer’s GitHub commits and read community updates on Discord or Telegram at least weekly. If the team suddenly goes quiet while the price spikes, treat the silence as an alarm — sell or reduce exposure until communication resumes. Ongoing dialogue is a simple but powerful health indicator for any crypto venture. 

Can the Industry Outpace the Scammers?

Scammers thrived in 2024 — losses to AI-driven pig butchering schemes jumped 40%. Yet shady transfers are becoming a smaller slice of the overall market — illicit volume has fallen almost 20% because legitimate activity is growing faster.

• ID checks at exchange front-ends: Many trading sites now require basic KYC before you swap tokens — making it harder for career scammers to reboot under new names.
• Live scam alerts in wallets: Good wallet apps simulate the transaction you’re about to sign. The swap is stopped cold if the contract tries to yank liquidity or block selling. 
• Shared blocklists: Wallets cross-reference every address you interact with against public scam databases and flash a warning before you hit “confirm.”
