Crypto Scams and Prevention [2026]: Read Before Investing

1. Crypto scam statistics

Fraud losses have grown alongside cryptocurrency markets. The original guide attributes to a Chainalysis report an estimate of approximately $14 billion, or ₩18 trillion, in worldwide cryptocurrency scam losses in 2025.

It also describes rising cryptocurrency fraud in Korea, attributing to police statistics a year-over-year increase exceeding 40% in reported virtual-asset crimes in 2025.

2. Ponzi schemes

How they work

Promoters recruit investors with promises of “10–30% guaranteed monthly returns.” Early investors may receive payments, but the money comes from new investors' principal rather than investment profits. The system collapses when new inflows slow.

Examples cited in the source

• BitConnect: Promised 1% daily returns; the guide cites approximately $3.6 billion in losses.
• PlusToken: Described as a major Chinese Ponzi scheme, with approximately $3 billion in losses.
• HyperFund: Promised 0.5–1% daily; approximately $1.7 billion in losses as cited here.

🚩 Warning signs

• Promises of a fixed return or principal protection.
• Recruitment bonuses in a multilevel structure.
• No clear explanation of how actual profits are generated.

3. Rug pulls

How they work

A new token or project attracts investment, then its operators suddenly withdraw liquidity and disappear. The source associates this mainly with DeFi projects and meme coins.

🚩 Warning signs

• Anonymous or unverifiable team members.
• The development team controls at least 50% of token distribution.
• The smart contract has not been audited.
• Excessive marketing on social media and Telegram.

4. Pump-and-dump schemes

How they work

Organizers buy a large amount in advance, then promote claims such as “This coin will rise tenfold!” across communities and social media. After the price rises, they sell at inflated prices and leave.

🚩 Warning signs

• Several channels suddenly recommend the same coin simultaneously.
• Artificial urgency: “Buy now or miss your chance forever.”
• Often involves small altcoins with little trading volume.
• You cannot verify whether the promoter already holds the coin.

5. Phishing and hacks

Fake websites, emails and direct messages steal private keys, seed phrases and exchange passwords.

Common patterns

• An email impersonating Binance says “Security alert—log in immediately” and leads to a fake site.
• A fake MetaMask connection request says “Connect your wallet to claim an airdrop,” leading to asset theft.
• A Telegram message says “We are customer support; please send your seed phrase.” The source identifies this as a scam.

6. Romance scams

Scammers exploit romantic feelings through social media or dating apps to induce investment. This is also called “pig butchering.”

A typical sequence

1. Approach through an attractive social-media profile.
2. Build an emotional bond over weeks or months.
3. Encourage investment by saying “I made a lot from crypto too.”
4. Direct deposits into a fake exchange app.
5. Allow a small initial withdrawal to establish trust.
6. Block withdrawals after a larger deposit, then disappear.

7. Fake exchanges and apps

Fake apps or websites closely imitate real exchanges to steal deposits. The source notes that they sometimes appear in the App Store or Google Play.

Checks

• Find app download links directly on the official website.
• Check the exact URL: for example, binance.com versus blnance.com.
• Review app ratings and download counts.
• Check the security certificate and HTTPS, as listed in the source's checklist.

9. What trustworthy investing looks like

The source says a capable trading system:

• Discloses losses as well as wins. Be suspicious of hidden losses.
• Does not promise guaranteed returns. Markets have no certainty.
• Can be checked in real time. Look at current results, not only old screenshots.
• Does not force investment decisions. It provides information and leaves judgment to you.

The guide describes NOONOO TRADING as transparently publishing every trade in real time, including wins, losses and all positions, and invites readers to verify this themselves.
