I understand the concept of a mixer and have succesfully used Blockchain.info wallet's shared send feature. The shared receiving address however confuses me. I assumed that one needs to click "new shared address" and then send the coins to the new address that is created. However after testing with tiny amounts I got really weird results, such as coins disappearing, mixing not working etc.
I am asking for a detailed step-by-step guide on how to use the feature as well as an explanation of the mechanism behind it. Thanks!
