The cryptocurrency landscape has grown exponentially over the past decade, attracting millions of investors worldwide. However, this rapid expansion has also opened the door to an alarming rise in scams and fraudulent schemes. In 2024 alone, illicit crypto transactions reached an estimated $51 billion**, with **$40.9 billion flowing into known malicious addresses—accounting for 0.14% of total on-chain volume.
High-yield investment program (HYIP) scams and “pig butchering” frauds made up 50.2% and 33.2% of these crimes respectively. With new tokens launching daily and investment opportunities flooding social media, it’s more important than ever to recognize the warning signs before you lose your hard-earned money.
Below are the top 10 red flags that signal a potential crypto scam—so you can invest wisely and avoid becoming the next victim.
Unrealistic Promises of High Returns
One of the most common—and dangerous—red flags is the promise of guaranteed, sky-high returns with little or no risk. Phrases like “Earn 10x in a week” or “Zero risk, maximum profit” should immediately raise suspicion.
Legitimate investments, especially in volatile markets like crypto, never guarantee profits. The now-infamous Bitconnect scheme lured investors with promises of daily returns, only to collapse in 2018 and cost users over $2.4 billion. It was later revealed to be a classic Ponzi scheme, where early investors were paid with funds from new entrants.

Pro Tip: If it sounds too good to be true, it almost certainly is. Always assess historical performance, market trends, and project fundamentals before committing funds.
Lack of Transparency and Anonymous Founders
Trust in crypto starts with transparency. A credible project will have a public team with verifiable identities, professional backgrounds, and active social media or LinkedIn profiles. When founders remain anonymous or use fake names and photos, proceed with extreme caution.
Many scams rely on fabricated teams with AI-generated headshots or outdated résumés. Check for:
- Public appearances (interviews, conferences)
- Past experience in blockchain or finance
- Consistent online presence over time
If team members appear suddenly, lack digital footprints, or vanish after launch, that’s a major red flag.
ICO Scams and Fake Whitepapers
An authentic whitepaper is the foundation of any serious crypto project. It should clearly outline the token’s purpose, technology stack, use cases, and development roadmap. Be wary of:
- Missing or poorly written whitepapers
- Copied content from other projects
- Vague technical descriptions
In 2018, research showed that over 80% of ICOs during the market boom were scams—many using plagiarized whitepapers to deceive investors.
Take the PlexCoin case: it raised $15 million by promising a 1,354% monthly return before being shut down by the U.S. Securities and Exchange Commission (SEC). Always verify the whitepaper’s originality and look for third-party audits.
Excessive Hype and Paid Celebrity Endorsements
Scammers often create artificial buzz using paid influencers and celebrity promotions. Just because a well-known personality tweets about a coin doesn’t mean it’s legitimate.
The Squid Game Token surged by over 230,000% in days due to viral marketing tied to the Netflix show—only for developers to pull the rug and disappear with investor funds. This “rug pull” left countless people with worthless tokens.
Remember: Real projects build value through innovation, not hype. Rely on due diligence—not Instagram ads or TikTok trends.
Requests for Upfront Payments or Private Keys
No legitimate crypto platform will ever ask for your private keys, seed phrase, or wallet password. These grant full access to your funds—sharing them is equivalent to handing over your bank account details.
Beware of:
- Fake customer support demanding fees for “withdrawal activation”
- Phishing emails impersonating exchanges like Coinbase
- Requests for payment via gift cards or wire transfers
👉 Learn how secure platforms protect your assets without asking for sensitive information.
If someone asks for your seed phrase, close the tab immediately. Legitimate services never require this.
No Real Utility & Pyramid Structures
A red flag becomes glaring when a project earns you money primarily by recruiting others—not through actual product use. This is a hallmark of Ponzi or pyramid schemes.
The OneCoin scam defrauded investors of $4 billion by promoting a fake cryptocurrency and rewarding referrals instead of offering real blockchain functionality.
Warning signs include:
- High commission rates for bringing in new users
- Earnings based solely on recruitment
- No working product or clear use case
Research shows 90% of new crypto projects fail within a year, largely due to lack of utility. Invest only in tokens with real-world applications.
Pump-and-Dump Schemes
In a pump-and-dump scam, insiders artificially inflate a coin’s price using coordinated buying and aggressive marketing—then sell off their holdings at peak value, crashing the market.
In 2021 alone, rug pulls and pump-and-dumps caused over $2.8 billion in losses. These schemes thrive on low-cap coins with minimal trading volume.
Watch for:
- Sudden, unexplained price spikes
- Massive transactions from unknown wallets
- Low liquidity before a surge
When retail investors rush in, insiders exit—leaving latecomers with near-worthless tokens.
No Clear Exchange Listings
Legitimate cryptocurrencies are typically listed on reputable centralized exchanges (CEXs) like Binance, Kraken, or OKX—platforms that conduct due diligence before listing.
Be cautious if a token is only available on obscure decentralized exchanges (DEXs) with:
- No KYC verification
- Limited trading pairs
- Difficulty withdrawing funds
Lack of visibility on trusted platforms often indicates higher risk or intentional avoidance of scrutiny.
Fake Partnerships and False Claims
Scammers frequently fabricate partnerships with big brands or influencers to gain credibility. The SaveTheKids token, promoted by several influencers, was abandoned shortly after launch despite claims of charitable ties.
Always verify partnerships by:
- Checking official company websites
- Reviewing press releases on legitimate news outlets
- Looking for social media announcements from verified accounts
If proof is missing or links lead nowhere, assume the claim is false.
Unverified Smart Contracts
Smart contracts power most DeFi and token projects—but un-audited code can contain backdoors that allow developers to steal funds.
In 2023, nearly $1.7 billion was lost due to vulnerabilities in smart contracts. To stay safe:
- Confirm the contract is publicly available on block explorers like Etherscan
- Look for audit reports from firms like CertiK or Hacken
- Avoid projects that hide their code or refuse transparency
An unaudited contract is a ticking time bomb.
