As a developer i interested to develop some platform like crypto mixer, but i don't really know if it still profitable or not at this trend, any clue?
Get onto Tor (The Onion Router). You can download and install the Tor Browser from here - https://www.torproject.org/.
Then go to this site - https://onionlinks.com/ - and follow all the links there in the Tor Browser..
Many of the links are mixers in action. They will give you some good ideas about how mixers should be used. Probably using Tor is one of the best ways to mix successfully.
