I'm trying to find a Bitcoin mixer that doesn't keep logs and offers longer delay periods – most I've seen only go up to 24 hours. I want to spread my transactions out over several days to make tracking harder. Also, the whole "distribution control" thing confuses me – some mixers let you adjust percentages manually, others don't. Anyone know a reliable service with delays up to several days and a solid no-logs policy? Would rather learn from someone's experience than just pick randomly.
