On-chain stablecoin (USDT / USDC)
Stablecoins combine crypto privacy with fiat price stability — the default choice for anonymous buyers.
Pros
- No personal data ever touches the merchant
- Settlements clear in minutes globally
- Price-stable, unlike volatile coins
Cons
- On-ramp still requires KYC at most exchanges
- Network fees on Ethereum can be painful
Verdict. The best overall choice for anonymous SMM payments. TRC-20 and Polygon keep fees negligible.
