According to the source, five major crypto scams circulating in 2025 are advanced phishing, rug pulls, impersonation, AI deepfakes, and fake support schemes. Scams remained the largest crypto-crime category by revenue in 2023, underscoring phishing’s outsized impact on trader losses, according to Chainalysis’ 2024 Crypto Crime Report. Rug pulls and exit scams continued to drive significant DeFi losses, reinforcing the need for contract due diligence, according to CertiK’s 2023 Web3 Security Report. Impersonation and fake customer support commonly begin on social media and messaging apps, with crypto investment scams among the top sources of reported consumer losses, according to the U.S. Federal Trade Commission’s 2023 Data Spotlight. Threat actors are increasingly using AI-generated audio and video to impersonate trusted figures and solicit transfers, according to FBI Internet Crime Complaint Center advisories from 2023–2024. Traders should harden operations by verifying URLs, using hardware wallets, and regularly revoking risky token approvals to limit PnL-impacting unauthorized transfers, according to Etherscan’s Token Approval Checker documentation and SlowMist security guidance.

According to @Flavio_leMec on Twitter, discussions around joining Telegram increasingly highlight its reputation as a hub for crypto trading, along with other activities. With the rise of crypto-related scams and trading groups on Telegram, traders are urged to prioritize security and 'stay safu' when engaging with new channels or communities (source: @Flavio_leMec, June 2, 2025). This underscores the importance of due diligence for crypto traders seeking alpha or signals on Telegram, as exposure to fraudulent schemes remains a critical risk.
