but the system might be a bit.... Complicated. Let's see how people manage to use it ^^
Not complicated at all. Try yourself and you will see how fast and simple it is to use them.
Send the coins -> Mix the way you want -> Withdraw the private keys -> Spend
This is actually the very reason why we have a service called ChipMixer. Had it been complicated then it would turn off many satisfied clients into other similar services around. It is easy to use, that is for sure and we should thank ChipMixer for this great product/service offering.
