I have been following the sinbad avatar campaign for 3 weeks. Today I just understood that in some cases, hiding bitcoin transactions may be necessary to protect our privacy from the public or for certain purposes. I have never had experience using a mixer, and if I may ask. How much does it cost for one mix? Service fees and network fees. Maybe I want to try it

Sorry, maybe my question is very basic, but I have no experience with mixers and I don't have much bitcoin so I thought I'd find out the actual costs involved. I hope those who answer have experience using a Sinbad mixer
