    The collateral fee which is paid randomly (10% chance) has been reduced from 0.01 to 0.0001 in the last year or so. The cheapness of mixing leads me to think that an attacker could run a lot of mixing clients to become the only mixing participant to some honest mixers. If you are only mixing with one person then the other person can know the source of your PrivateSend transactions.

    The way i understand is that Dash always needs an minimum of 3 participants to mix, which can extend to 5 participants (i'm not totally sure about this last part)

    Do you know how the participant is defined here? How is it prevented that the the other 2, 3 or 4 participants are not the same entity?
