What are the benefits of chipmixer giving out free service? Maybe ads or premium users? But many thanks for your tipps, will definitivly try that service.
No fee, donations only
You pay what you want
They accepts donation if you like their service than you can simply press donate button when you are mixing.
I have also made few donation to them before, I am also quite anxious about their signature campaign which is paying out good amount of bitcoin everyweek. How they can afford that
They are getting huge donations everyday?
