initially halt mixing if no other users boxes are present, but only initially for the fist round.

Currently, for example, If i submit 200 erg in 2, 100 spots, it will mix against myself even if no others are present. If it mixes for 20 rounds and someone joins at round 21, that's great, but, I've just wasted 20 rounds of tx fees since it's pretty obvious who mixed if i'm the only one up to those 20 rounds (essentially those twenty rounds were not needed because nothing matters until the other person joins in).

idea would be to have the mixer just wait until someone else joins then start mixing...even if the other person pulls out after one round, it would still make it a 50/50 guess after that initial mix of two users.

sounds like it doesn't mix with itsself ever...which would create a traceable event...suggestion would be to not self mix until someone else is present, then, it can mix with whomever as well as itsself.
