Bitcoin mixers (a.k.a. tumblers or blenders) improve privacy by breaking on-chain links between your source inputs and destination outputs. In 2022–2023 the market matured: fees became transparent, delays and multi-output features improved, and more services moved to non‑custodial or proof‑of‑reserve approaches.

Key features to evaluate

• Custodial vs non‑custodial workflow
• Service fee range and output fee model
• Transfer delays and randomization
• Multi‑output support and address types
• Code of mixing to avoid self‑relinking

Operational recommendations

Use fresh addresses, avoid reusing change, prefer randomized delays and amounts, split outputs, and keep the mixing code safe to prevent linking to your previous mixes.

Always verify that you control the destination addresses and follow your jurisdiction’s compliance requirements.
