- Crypto-Only Payments: Legitimate vendors offer multiple payment options
- No Contact Information: If you can’t reach them, don’t trust them
- Poor Website Quality: Grammar errors and unprofessional design suggest lack of investment in quality
- No Physical Address: Legitimate businesses have verifiable locations
- Unrealistic Claims: Vendors promising miraculous results should be avoided
