There is often a weak point in these mixing systems, and that is that somewhere in the world there must be a computer/s doing the mixing, and how can we trust that computer is not being monitored somehow.
tell me which would you prefer to use if let say both of these are 99% anon:
1) 99% of all Anon coins out there that is using mix-node
or
2) Crypt hard-to-trace p2p wallet to wallet and no mix node.
well if both are 99% secure/anon then it really wouldn't cause me much interest tbh, or cause any major uptake by sellers , I think it would need to be ground breaking tech to cause the kind of uptake people are talking about to cause the prices people are hoping for , I do get your point though that no.2 sounds "slightly" better, but do I think people/sellers will dump the old anon solutions and flock to crypt cos its version of "99% anon" sounds better = NO.
