I do not think so, with the rate people are making bitcoin transactions. If you look at the amount of fee mixers are charging their customers, it is also not also small at all and many people do not think about the fee.
Your mixer changes from 0.7 to 4.7%.
If you make a deposit the mixer has to move the coins you sent, they also have to send you the mixed outputs, that's two tx at least, not including at least one just the bare minimum before the final output as they don't want to pay directly from, splitting that in half since they can use multiple outputs, that and you got at the current fees around 30$ in fees if the user chooses 0.7% and mixes $1000 worth of BTC your mixer loses $24 every mix.
Love how the whole thing has become so elitist right now, the fees are nothing if you move or mix $10k otr $100k worth of BTC, because yeah, that's your average Joe money for the week around here, right?
Want to say the same thing on which if you are that someone who do really tend to mix out 10k or even 1k worth of coins then even up paying $20-30 when it comes to fees then it wont really be that an issue.
Not to make out some discrimination about into those small time mixer users to be mindful about the fees. We do know that mixing services arent the ones who are mainly affected with this recent surge
of network transactions which we know that this isnt something a condition that do happen often.If it turns out that there would really be some additional fee then it would be understandable that mixers would really be just adjusting basing up on to those dynamic fees. It might look that much reaching about 4.7% then it would be on your choice whether you would be proceeding or not.
Just like on what i have said which people who do make use of these mixers arent talking about small amounts that they are transacting.
So fees wont really be that issue basing up on the privacy that it do gives. So it wont be that much of an issue.
