Worked example: 0.5 BTC mix
Send 0.5 BTC to the deposit address. Here's exactly what arrives at your receiving address.
Transaction limits
Min 0.001 BTC, max 1 BTC.
Both bounds are deliberate. The minimum keeps small amounts from standing out in the anonymity set. The maximum keeps individual transactions in an unambiguous range.
Minimum — 0.001 BTC
Very small amounts mix poorly — they stand out in the anonymity set, and the fixed 0.0001 BTC network fee would represent a disproportionate share of the value.
Maximum — 1 BTC
Anonymity sets are denser at moderate values; very large transactions are easier to fingerprint by size alone. Larger amounts should be split across multiple mixes.
Comparison
Pricing across approaches.
Cost is one factor. The underlying protocol, transparency about logs, and operator reputation matter at least as much.
