Does this only 0.4% fee makes the Tumblers, the most cheapest and yet most effective mixer that can be used by an average person ?
As i see the reviews in the review campaign were satisfactory.
From the OP, the transaction fees are easily comparable, go there and compare the listed mixers.
I was one of the people that first review the site before some corrections were made, it is a good mixer. If you use the timber ones, you will also get fee discount if you use your tumbler code the next time you want to make use of the mixer.
