If you’re looking for a mixer which neither keeps any logs, nor asks you to register; CRYPTOMIXER is an option you can peek at. It does offer registrations in case you’d want to keep things professional, organized and are a frequent mixer. It’s one of the very few mixers which offer “multiple deposit addresses” (upto 5); so you can break the deposit into multiple parts which add upto your total amount. Even offers 2-FA (via PGP) for account security. It also acts as a BTC àXMR à BTC convertor which further adds anonymity. The fee is randomized between a minimum 1% and a maximum 4%. Minimum Withdrawal and deposit limits are acceptable, currently 0.00045 BTC and 0.0018 BTC respectively. Upto 10 additional addresses supported for each output. Time-delays aren’t completely user-controlled, yet users get to specify the maximum delay they want for the total output. All outputs are processed before this timer is reached. Instant withdrawal too available.
